eslint output indentation breaks problem matcher (Nx monorepo support)

[fregante]

Description:

Annotations don't appear when eslint is indented. This happens when using tools like https://nx.dev that orchestrate and group script/tasks in large repos.

It seems that Jest's matcher is not affected

Hello @fregante👋,
Thank you for reporting this issue and for submitting the related pull request! To help us investigate and understand the problem better, could you please provide a minimal repository that demonstrates the issue?
Your cooperation is greatly appreciated!

Please use the example strings provided in my opening post. Setting up the entire repo just to produce the same output is a bit much.

The exact repro is:

- uses: actions/setup-node@v4
- run: |
    echo "  /home/runner/work/repo/file.ts"
    echo "    14:1  error  'webext-messenger' should be listed in the project's dependencies. Run 'npm i -S webext-messenger' to add it  import/no-extraneous-dependencies"

You can find the fix in my PR already: #1245
