fix : ci: skip tests for doc-only changes

[Dibbu-cell]

Description

Add paths-ignore to generated test workflows so CI skips running tests when only documentation files change.

• updated scripts/split_tox_gh_actions/templates/base.jinja to add paths-ignore for '/*.md', 'docs/', 'README.md', 'CHANGELOG.md'
• regenerated workflows under .github/workflows

Issues

• resolves: Ensure the Python SDK sets sentry.origin for Structured Logs according to the documentation #4907

Reminders

• Please add tests to validate your changes, and lint your code using tox -e linters.
• Add GH Issue ID & Linear ID (if applicable)
• PR title should use conventional commit style (feat:, fix:, ref:, meta:)
• For external contributors: CONTRIBUTING.md, Sentry SDK development docs, Discord community
