support installation from git remotes via git clone

[kevinushey]

For example:

> pak::pkg_install("git::git@github.com:rstudio/gt.git")
Error: 
! error in pak subprocess
Caused by error: 
! Could not solve package dependencies:
* git::git@github.com:rstudio/gt.git: ! pkgdepends resolution error for git::git@github.com:rstudio/gt.git.
Caused by error: 
! Failed to download DESCRIPTION from git repo at <://git@github.com:rstudio/gt.git>.
Caused by error in `(function (e) …`:
! URL rejected: Port number was not a decimal number between 0 and 65535
Type .Last.error to see the more details.

The equivalent remotes invocation works.

> remotes::install_git("git@github.com:rstudio/gt.git")

SSH is not supported, only HTTPS:

pak::pkg_install("git::https://github.com/rstudio/gt.git")

Is this something that might change in the future, or should I discourage this in renv? I suppose I could also transform such SSH URIs into https URIs, at least for GitHub.

[gaborcsardi]

It is unlikely that it would change any time soon.
