fix(lsp): code actions capabilities

[ematipico]

Summary

This PR is a follow-up of #3731

The reason why that PR failed is because we forgot to add other code actions required for lint rules to work.

This PR adds those actions.

Test Plan

I manually tested the new code.

I can still see the code actions emitted by the lint rules (fix and suppression), and the safe fixes are applied on save.

When, for example, source.fixAll.biome is set to false, it isn't applied, which is what we want.
