Making sure tests can be run and pass, on Linux

[lahodaj]

This patch fixes a few things around running tests + adds them to the GH Actions pipeline.

Specifically:

• ant test-vscode-ext now passes on Linux (cannot try on Mac).
• to do that, I needed this fix: Adjusting command name for surround.with. apache/netbeans#6771 , so including it as a patch.
• the order of application of patches is becoming important, so manual git apply * may or may not work, depending on FS order. Tried to tweak the script to use git apply + avoiding duplication of the patch names (auto-reversing the list).
• updates to BUILD.md to reflect all this + entry in the GH workflow

I hope the necessary tests run successfully now

I tested patch application as well as build/test on Mac OS. All fine.
