Update treesitter configuration to use master branch

[LuisAaronGoicochea]

Specify the use of the 'master' branch for compatibility with Lazy loading.

Hi Josean!
I noticed a small compatibility issue with Lazy loading and the Treesitter config, so I updated it to explicitly use the master branch.

This should avoid potential loading inconsistencies and keep things aligned with Lazy’s recommendations.

Thanks a lot for the great content and for sharing this config!
