Support renovating Terrafrom Modules from private Git repositories using shallow clone URL argument

Type of discussion.

I'm proposing an idea

Tell us more.

Hi folks,
Renovate already supports the following format of source URLs for Terraform modules:

git::ssh://git@git.example.com/modules/foo-module.git//hub?ref=v7.1.0

Based on Terraform documentation, users can also specify an additional depth argument in the URL

git::ssh://git@git.example.com/modules/foo-module.git//hub?depth=1&ref=v7.1.0

The currently used Regex doesn't support the argument - https://regex101.com/r/RASnRo/1

That is blocking our usage of Renovate at the moment, as we leverage shallow clone to save time during terraform init

I propose slightly modifying the regex to allow parsing the URLs even with the depth argument specified https://regex101.com/r/RASnRo/2

(?:git::)?(?<url>(?:(?:http|https|ssh):\/\/)?(?:.*@)?(?<path>.*\/(?<project>.*\/.*)))\?.*ref=(?<tag>.*)$

instead of

(?:git::)?(?<url>(?:(?:http|https|ssh):\/\/)?(?:.*@)?(?<path>.*\/(?<project>.*\/.*)))\?ref=(?<tag>.*)$  

I'm ready to submit a PR with that change if you consider it a good idea.
Many thanks for considering my request.
