* [backport][stable-2.15] 🧪 Replace GitHub SVN integration test with local TLS
PR #82334
* Run svn integration test locally with TLS
This patch uses a `trustme` to make an ephemeral CA, and server, and
client TLS artifacts for testing. These are integrated into the Apache
web server via it's `mod_ssl`.
Resolves#82207
* Replace GitHub SVN HTTPS URL w/ localhost over TLS
This change gets rid of the need to use GitHub, which is just about to
drop support for SVN [[1]]. Moreover, it eliminates the need to use
external network for any SVN commands in the test.
