Thank you for accepting my PR, though I missed that all the checks failed.
We will pass the checks if we do the following.

• Julia 1.6 and Julia nightly workflows: This is because we use the depreciated cache package in the workflow. We must use actions/cache@v3 or @v4. Refer to : https://github.blog/changelog/2024-12-05-notice-of-upcoming-releases-and-breaking-changes-for-github-actions/#actions-cache-v1-v2-and-actions-toolkit-cache-package-closing-down
• Documentation workflow: The BaryChebTools module is not refered in the Documentation. Also, the docstrings of barycheb and barychebinit look to be broken. We should fix them.

I also find that Julia version should be 1.6 or higher from the requirement of FastGaussQuadrature.jl.

I would like to revise my branch.

I revised my branch to include Julia version 1.6 and docstrings of the BaryChebTools module.

However, I cannot handle the depreciated cache package problem because I do not have permission to update .github/workflows/CI.yml.
Could you please modify the line of 26th of CI.yml from actions/cache@v1 to actions/cache@v4 ?
Then, I will prepare my branch as diffs to the latest master's.

I've updated the master branch. Please go ahead.
