Rename "master" branch to "main"

[gclough]

The current practice is to use main for the main branch, instead of master... so we should swap, to keep up-to-date:

or you could leave it alone and be stable instead of trendy

Strongly agree with renaming the main branch to something other than master. Only concern is whether this will interfere with how galaxy works.

Going to point out that these days GitHub defaults to main. What would be needed to make this change, other than updating CI flows?

will make this change as part of overall modernization of the anxs roles, including changing the namespace to be in compliance with current galaxy specs.
