fix(linter): update allowed ESLint config file extensions (#30127)
ESLint added experimental support for typescript config files since
[9.9.0](https://eslint.org/blog/2024/08/eslint-v9.9.0-released/#experimental-typescript-configuration-files),
and as of
[9.18.0](https://eslint.org/blog/2025/01/eslint-v9.18.0-released/#stable-typescript-configuration-file-support)
that support is stable. This PR add ts/mts/cts to the list of known
eslint config files, and adds the same extensions to config file
generators

## Current Behavior
When using the eslint executor with a ts file, returns error "When using
the new Flat Config with ESLint, all configs must be named
eslint.config.js or eslint.config.cjs and .eslintrc files may not be
used. See
https://eslint.org/docs/latest/use/configure/configuration-files"

When using the eslint plugin, the inferred task is not created for
projects that do not have a non-ts eslint config.

### Workarounds
- Compiling ts rules/configs in a project. Introduces other issues
- Using jiti or comparable
- For plugin users, having a fake eslint.config.js at the root allows
the inferred task to be created. ESLint will still use the ts config.
  - Cache targets are wrong
  - Complications in non-monorepo workspaces

## Expected Behavior
When using the eslint executor with a ts file, no error is thrown.

When using the eslint plugin with a ts file, the inferred task is
created.
