Remove `master` branch in favor of `main`

[Xieql]

What would you like to be added:

Removal of the master branch.

Why is this needed:

We currently have both main and master branches in our repository, which could potentially confuse users or developers.

To simplify and avoid confusion, we can remove the master branch and using main as our primary branch.

if we do it, we may need consider:

• Update CI/CD Configurations: Check and adjust our continuous integration and deployment tools to ensure they are not relying on the master branch.
• Update Documentation: Scan and update all documentation, guides, or any references that mention the master branch, replacing them with main.
