Purpose of this PR

Adds an ARM lease entry for the new Monitor TraceAssociations service so design-review ownership and lease duration are explicitly tracked under .github/arm-leases.

• New resource provider.

• New API version for an existing resource provider. (If API spec is not defined in TypeSpec, the PR should have been created in adherence to OpenAPI specs PR creation guidance).

• Update existing version for a new feature. (This is applicable only when you are revising a private preview API version.)

• Update existing version to fix OpenAPI spec quality issues in S360.

• Convert existing OpenAPI spec to TypeSpec spec (do not combine this with implementing changes for a new API version).

• Other, please clarify:

  • Add lease metadata for monitor/Microsoft.Monitor/TraceAssociations (duration: 120 days, reviewer: @tejaswiminnu).
