feat: Improve Git error output when calling Telescope git command in non-git directory

[RoRep1ay]

Description

Currently, when you're calling :Telescope git_command on a non-git directory, it's outputting an error exception detailing that current directory is not a directory. I don't think this error trace is necessary, just outputting message that current directory is not a git directory is enough .

Before:

After:

Type of change

Configuration:

• Neovim version (nvim --version): NVIM v0.8.3
• Operating system and version: Mac OS Ventura

Checklist:

i prefer not to use vim.notify for some things that can be used for scripting. using vim.notify completly removes this ability to allow users to script around errors.

#2225 tries to resolve this and i plan to finish it.

we already merged this and had a whole discussion here on why we probably dont want to do it like that. #2181
