install_gitlab() should pass quiet to gitlab_pat()

[MichaelChirico]

formals(remotes::install_gitlab)[c('auth_token', 'quiet')]
# $auth_token
# gitlab_pat()

# $quiet
# [1] FALSE

formals(remotes:::gitlab_pat)
# $quiet
# [1] TRUE

Seems it would be simple & consistent to pass quiet on to gitlab_pat. Will file a PR shortly.

This is currently actually what we want, the install functions default to not being quiet, but we don't want to print output every time the PAT is looked up.

The quiet argument exists in gitlab_pat() and github_pat() only for debugging purposes when it is called directly.
