fix: "standard" is not caught as correct provider

[Tchoupinax]

Hello,

I tested your project and I had a weird error with my git configuration (I am using a self hosted instance of Gitea)

Failed to get git provider: unknown provider: standard

I was really suprised so I read the doc again and again, it says the standard provider is possible.

I finally went to the code and caught this switch case where the expected provider value is git, not standard. According to the fact that document says standard everywhere and the code calls it standard too, I guess the correct thing to do here is to rename git.

It works when I set provider: git in the TerraformRepository spec :)

Thank your for your work!

Hello @Tchoupinax,

Thanks for catching this bug! I guess I did not test enough the use of standard git authentication 😅

I'll merge it this week along with a new patch release.
