• VS Code Version: 1.53.2
• OS Version: Manjaro unstable
• Git Version: 2.30.1

Steps to Reproduce:

1. Execute git.clone command
2. Enter https git url for a private repository (does not even need to exist, so for example https://gitlab.com/haasef/test.git)
3. Askpass pops up with Git: https://gitlab.com': (Press 'Enter' ...) (The last two characters ': are from the host string and not the template)

Why is this an issue?

1. It does not create a problem when using the direct clone or github credentials provider (since that one does not check equality but only if github.com is contained)
2. But: when adding a new credentials provider that checks for the explicit url, it fails (see gitlab-vscode-extension)
3. This should have been fixed in Sometimes Git can't authenticate against GitHub #115037 but the fix does not handle a : in the end

More Information:

• askpass-main recieves:

  [
    "/home/felix/Documents/coding/vscode/.build/electron/code-oss",
    "/home/felix/Documents/coding/vscode/extensions/git/out/askpass-main.js",
    "Username",
    "for",
    "'https://gitlab.com':",
  ]
  

• and parses the host as https://gitlab.com': instead of https://gitlab.com

Suggested fix:

Does this issue occur when all extensions are disabled?: Yes (Was tested and debugged on master)
