Added path filter to validate.yml

[jasonjoh]

So now the validation will only run if relevant files are changed. There's no reason to run validation on sample queries if only permissions files are changed, for example.

Also added an opposite-filtered version of the workflow in validate-patch.yml. This will allow us to make this a required status check on PRs without blocking PRs that don't touch relevant files. See https://github.com/orgs/community/discussions/44490 for context.

Pull Request Overview

This PR adds path filtering to GitHub workflow validation to optimize CI runs by only executing validation when relevant files are modified. The solution addresses the issue where required status checks would block PRs that don't modify validation-relevant files.

• Added path filters to validate.yml to run only when sample queries, scripts, tests, or package files change
• Created validate-patch.yml as a complementary workflow that passes for PRs not touching relevant files
• Implemented solution for GitHub's required status check limitation using paths-ignore pattern
