fix(ci): 🛡️mitigate CVE-2025-6176 by pinning brotli to patched commit and upgrading dev dependency pins (#4802)

# Description of Changes

This pull request updates the development requirements to address
security vulnerabilities and improve dependency management. The most
important changes include switching the `brotli` dependency to a
specific commit for CVE mitigation, and upgrading the `filelock`
package.

**Security and Dependency Management Updates:**

* Pinned the `brotli` package to a specific commit from the official
GitHub repository in both `requirements_dev.in` and
`requirements_dev.txt` to mitigate CVE-2025-6176. This replaces the
previous PyPI version and removes hash checks, ensuring a secure and
up-to-date version is used.
