Dhruv Manilawala aa429b413f Check diagnostic refresh support from client capability (#15014) ...

## Summary

Per the LSP spec, the property name is `workspace.diagnostics` with an
`s` at the end but the `lsp-types` dependency uses
`workspace.diagnostic` (without an `s`). Our fork contains this fix
(0f58d62879)
so we should avoid the hardcoded value.

The implication of this is that the client which doesn't support
workspace refresh capability didn't support the [dynamic
configuration](https://docs.astral.sh/ruff/editors/features/#dynamic-configuration)
feature because the server would _always_ send the workspace refresh
request but the client would ignore it. We have a fallback logic to
publish the diagnostics instead:
