.github/workflows,script/cibuild: drop custom Perl

Since commit c591ff7 of PR git-lfs#3125 we
have installed Strawberry Perl before running our CI test suite on
Windows.  This was necessary when we used the AppVeyor service to run
our test suite on Windows, and subsequently also when we converted our
CI jobs to GitHub Actions in PR git-lfs#3808.  We require Perl because we use
the "prove" command, which runs all of our t/t-*.sh test scripts and
collects and summarizes the results.

However, since commit 8818630 of
PR git-lfs#5666 we have installed the Git for Windows SDK before running
our test suite, and it includes a full Perl distribution, which means
we no longer need to install Strawberry Perl separately.
