#35691 adds support for new code actions to configure code style options and diagnostic severity from light bulb, but the code actions were disabled by 55416aa towards the end of the PR. Enabling these code actions is blocked on following items:

1. All the editorconfig features in compiler, project system and IDE layers are enabled by default. In absence of any of this hooks, the code action does not work as expected.
2. Different .editorconfig severity strings are used to specify IDE code style options and dotnet_diagnostic.severity #35690 leads to the generated severity entries by this code action not being respected by the compiler.

Once the above two have been resolved, we should revert the following commits from #35691, which should enable the code actions and unskip relevant tests:

1. 55416aa
2. 1be6eaf
