Scripts: Update branches with main and create new ones.

[spinillos]

The releasing script fails when it tries to create a new branch. It suppose to happen here but not working. Creating manually also doesn't work because the current generated code have diffs with the new branch.

So to make it works, the script should do the following:

• Fix create a new branch in foundation-sdk when we add a new release version.
• Sync branches with main branch.
