fix(renovate): valid regex

[gberenice]

what

• For fileMatch, we should use regex pattern, not globbing.
• I'm confused why trunk check didn't fail for previous PR, because this obviously is an issue:

❯ trunk check .github/renovate.json5 --show-existing

Walkthrough

This change updates the file matching patterns used by Renovate for Terraform files within the .github/renovate.json5 configuration. Specifically, it replaces the previous glob patterns "**/*.tf" and "**/*.tofu" with regular expression strings "\\.tf$" and "\\.tofu$". This adjustment alters how Renovate identifies and processes Terraform and OpenTofu files, shifting from glob-based matching to regex-based matching for greater specificity or compatibility. No changes were made to exported or public entities.

21-24: Correct usage of regex patterns for Renovate's fileMatch

The change from glob patterns (**/*.tf, **/*.tofu) to regex patterns (\\.tf$, \\.tofu$) is appropriate and fixes the invalid regex error. Renovate expects regex patterns in the fileMatch configuration rather than glob patterns, which explains why the trunk check was failing previously.

This is a good fix that ensures Renovate will correctly identify Terraform and OpenTofu files for dependency management.

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
