Windows: check what setting default branch does

[rkdarst]

• Check what the effect of setting default branch to main is. Instructions already say to do this, and I have no reason to think it's wrong, but we can make sure it's nothing unexpected.

From a default setup (with some options like notepad++). Looks like config is reasonable

$ git config --list
diff.astextplain.textconv=astextplain
filter.lfs.clean=git-lfs clean -- %f
filter.lfs.smudge=git-lfs smudge -- %f
filter.lfs.process=git-lfs filter-process
filter.lfs.required=true
http.sslbackend=schannel
core.autocrlf=true
core.fscache=true
core.symlinks=false
core.editor="C:\\Program Files\\Notepad++\\notepad++.exe" -multiInst -notabbar -nosession -noPlugin
pull.rebase=false
credential.helper=manager
credential.https://dev.azure.com.usehttppath=true/
init.defaultbranch=main

Seems like it does what it should in the config.
