LinkML Patterns should generate JSON Schema Patterns
**Describe the bug**

Specifying a [LinkML Pattern](https://linkml.io/linkml-model/docs/pattern/) in a **TypeDefinition**, for example, results in a pattern in a JSON-LD `pattern` attribute. But it doesn't generate a [JSON Schema `pattern`](https://json-schema.org/understanding-json-schema/reference/string.html#regular-expressions).

**To reproduce**
Steps to reproduce the behavior:
1. Create a schema with a pattern in any of the [Applicable Classes](https://linkml.io/linkml-model/docs/pattern/#applicable-classes)
2. Generate JSON-LD
3. Confirm the `pattern` attribute appears
4. Generate JSON Schema
5. Confirm the `pattern` does NOT appear

**Expected behavior**
The resulting JSON Schema has the specified pattern.

**Additional context**
JSON-LD patterns cannot be validated with COTS software. Whereas [JSON Schema `pattern` entries](https://json-schema.org/understanding-json-schema/reference/string.html#regular-expressions) can be validated with any JSON Schema validator.
