git clone intermittently fail for "Encountered end of file" by HTTPS protocol, Could we support SSH protocol

**Describe the bug**
git clone intermittently fail for "Encountered end of file" by HTTPS

**To Reproduce**
`rm -rf STF ; git clone https://github.com/adoptium/STF.git`


**Additional context**
I change HTTPS to SSH, then git clone always success(on the same machine):


Maybe this issue only occur in CHINA?

So, can we support ssh git?
When the test env USE_GIT_SSH=true, then git clone by ssh protocol.

**patch draft**

[support-git-ssh.diff.txt](https://github.com/adoptium/aqa-tests/files/8949097/support-git-ssh.diff.txt)

Start by reading the clone sites in buildenv/jenkins/getDependency, compile.sh, external/tomcat/test.sh, get.sh, and perf/bumbleBench/build.xml, then trace how USE_GIT_SSH is supplied from the test environment. Done means all listed GitHub clones use SSH when the setting is true and retain HTTPS behavior otherwise; exercise the relevant build or test entry points to verify both paths.
