Executable filename changed on Linux

[gadfly3173]

sourcegit_8.10.linux-x64.tar.gz from release use filename sourcegit, while linux-x64 from Github Actions use SourceGit. Is this excepted behavior? The new filename is not compatible with .desktop.template provided under v8.8.

I'll change the .github/ci.yml to use lowercase name for linux packages (which is the common style for executable files on most Unix-like systems).
