I know this will not be of any help to you but I too was interested in
trying out the babel from github repo.

I was confronted with same problem as you which I attempted
to solve via editing by hand the ins file.

But even after having done that I ended up with  a babel.sty (the only
file I was interested in), which was unusable for me from containing
Lua code

I believe build is supposed to use lua, there is a build.lua script.

In the end I simply "git diff" with the 3.44 version to identify
the change I was interested in in file babel.dtx, and I copied pasted directly
into a local copy of current babel.sty in my working repertory
the relevant modification.

I could then test succesfully the fix to the issue I was interested in

(I think this is #30 in github repo, but it was closed without
linking to the actual commit solving it ; not that that was
a big riddle to solve as it was naturally the latest commit as of
today in the repo :) )

I know it does not help...

Best,

Jean-François
