Keeping v1 commands available in v2 may confuse users
## Overview

In [Legacy subcommands § Command Line Options — aqtinstall 2.0.0 documentation](https://aqtinstall.readthedocs.io/en/v2.0.0/cli.html#legacy-subcommands), we wrote:

> The subcommands `install`, `tool`, `src`, `doc`, and `examples` have been deprecated in favor of the newer `install-*` commands, but they remain in aqt in case you still need to use them.

After reading the above paragraph, I will think *"Fine, 'aqt tool' is still there. Those guys are keeping two series of commands in v2. I don't have to update my script after upgrading aqtinstall"*. However, the reality is that after switching to v2, the old script will **NOT** work without modification, at least for the "tool" command.

## Test

A working example for installing QIFW by aqtinstall 1.2.5:

```console
$ aqt tool linux tools_ifw 4.1.1 qt.tools.ifw.41
Specified target combination is not valid: linux tools_ifw qt.tools.ifw.41
...
Time elapsed: 8.37262754 second
```

The same script does not work in 2.0.0:

```console
$ aqt tool linux tools_ifw 4.1.1 qt.tools.ifw.41
usage: aqt tool ...
...
aqt tool: error: argument target: invalid choice: 'tools_ifw' (choose from 'desktop', 'winrt', 'android', 'ios')
Error: Process completed with exit code 2.
```

Rewrite the script according to the documentation of "[install-tool](https://aqtinstall.readthedocs.io/en/v2.0.0/cli.html#install-tool-command)" but keep the *legacy* "tool" command. It works in 2.0.0:

```diff
- aqt tool linux         tools_ifw 4.1.1 qt.tools.ifw.41
+ aqt tool linux desktop tools_ifw
```

```console
$ aqt tool linux desktop tools_ifw
aqtinstall(aqt) v2.0.0 on Python 3.8.10 [CPython GCC 9.4.0]
Warning: The command 'tool' is deprecated and marked for removal in a future version of aqt.
In the future, please use the command 'install-tool' instead.
...
Time elapsed: 11.00345962 second
```

Add the "tool variant name":

```diff
- aqt tool linux desktop tools_ifw
+ aqt tool linux desktop tools_ifw qt.tools.ifw.41
```

```console
$ aqt tool linux desktop tools_ifw qt.tools.ifw.41
aqtinstall(aqt) v2.0.0 on Python 3.8.10 [CPython GCC 9.4.0]
Warning: The command 'tool' is deprecated and marked for removal in a future version of aqt.
In the future, please use the command 'install-tool' instead.
...
Time elapsed: 9.82558412 second
```

*Use the command 'install-tool' instead*:

```diff
- aqt tool         linux desktop tools_ifw qt.tools.ifw.41
+ aqt install-tool linux desktop tools_ifw qt.tools.ifw.41
```

```console
$ aqt install-tool linux desktop tools_ifw qt.tools.ifw.41
aqtinstall(aqt) v2.0.0 on Python 3.8.10 [CPython GCC 9.4.0]

## Conclusion

As you can see, in aqtinstall v2, "tool" is not a legacy subcommand but **another name** of "install-tool". Those old interfaces have been changed, so keeping them available in v2 may confuse users.

I really know that the API changes can be (or should be) made in a new major release, but we didn't keep the availability and compatibility for those legacy commands, and what's worse is that we didn't document it correctly and clearly.

## Ignorable possible solutions

Here are some expensive ways to solve this problem:

- Remove those legacy commands in the next major version and release this new version as soon as possible. Yes, aqtinstall v3.
- Or, make those legacy commands usable again in the next minor version of v2. In other words, keep two series (v1 and v2) of commands in aqtinstall ^v2.1.
