clear_diagnostics sends a publishDiagnostics notification without checking the client capabilities

[pyscripter]

Summary

Whilst publish_diagnostics checks client capabilities for supports_pull_diagnostics before sending a notification,
clear_diagnostics sends a publishDiagnostics notification without doing so.

Although it does not do much harm, I think it should do the same check as publish_diagnostics

@MichaReiser The fix is for ty. Please apply the same fix to the ruff server. https://github.com/astral-sh/ruff/blob/f0d0b5790079cc38ec0f4b34d771a056f1cd1481/crates/ruff_server/src/server/api/diagnostics.rs
