preview-build: Add path-pattern-ignore

[reakaleek]

So we can ignore some files and so that the files are not included in the comment.
(I'm not 100% sure if the files will actually be excluded from the changed_files output. But that is my assumption)

To be explicit, I know I want to ignore the following in the elasticsearch repo:

• Everything under /docs/reference/query-languages/esql/kibana
• Any README.md file

• Any README.md file

Then you could use:

with:
  path-pattern-ignore: docs/reference/query-languages/esql/kibana/**/README.md

Sorry it's two separate things:

• any .md file under /docs/reference/query-languages/esql/kibana
• and any random README file under docs

Because we're doing this centrally I assumed you'd have to do it all in one place, how would we configure this per repo? (forgive me I probably just haven't thought about this enough)

You can change the configuration here: https://github.com/elastic/elasticsearch/blob/main/.github/workflows/docs-build.yml

And then you can actually do:

with:
  path-pattern: docs/**
  path-pattern-ignore: |
    docs/reference/query-languages/esql/kibana/*.md
    docs/**/README.md

Confirmed ✅:

In e14aedb I modified both
docs/testing/req.md and docs/testing/cross-links.md, while adding path-pattern-ignore: docs/testing/req.md.

Only the docs/testing/cross-links.md appeared in the comment.
