Support Git Bash shell integration automatic injection

[IllusionMH]

There are various issues regarding integration for various shells, but for Windows it's limited to standalone pwsh, and there are open issue for WSL.

So request here is to support Git Bash as well as it's go to terminal if you install Git for Windows.

Are there plans to support it in near future?

I'm hesitant committing to this as weird things often happen with how git bash interacts with conpty. Could be a good community contribution though.

I tried setting up a profile based on the existing bash script:

"Git Bash+": {
  "source": "Git Bash",
  "args": ["--init-file", "C:\\Github\\microsoft\\vscode\\src\\vs\\workbench\\contrib\\terminal\\browser\\media\\shellIntegration-bash.sh"]
},

It does look like the sequences get through correctly, the same problems as on wsl (#143761) with decorations are happening though:

So I'd expect the work here to include:

• Waiting until Support shell integration on WSL in a local window #143761 is done
• Handle git bash properly within https://github.com/microsoft/vscode/blob/77abae96a780338d9b395ef7f6ef153607b5be99/src/vs/workbench/contrib/terminal/browser/media/shellIntegration-bash.sh, for example running the correct .bashrc

Thanks for the interest, git bash was on hold in #143769 due to some issues I thought would apply to it since running WSL in a sub-shell had some problems. I just tested it with @meganrogge now and it seems to work pretty well and a minor change will improve it further. So I think for August we'll try adapt the bash shell integration script to support MINGW/Cygwin/etc. and then document it as a manual install only/experimental option on the website https://code.visualstudio.com/docs/terminal/shell-integration#_manual-installation

I'll keep this issue open until it's non-experimental, making a note to write a test for endgame

• Git Bash is Windows hint: Send IsWindows when running bash shell integration on Windows #157697
• Docs update: Add a git bash section to shell integration vscode-docs#5559

Similar to the fish support #139400, we'll keep this open for now until we get automatic injection setup.

How can we test this in git bash?

To verify open git bash via the terminal profile picker and make sure the shell integration circle shows on the left side
