dotfiles: tilde sign in git repository URL is not allowed

[winkelmv]

Problem

Since dotfiles v1.2.4, the git repository URL is validated using a regex. In my company's Bitbucket setup, the user repository URLs always include a tilde (~) sign, e. g. like that:
ssh://git@bitbucket.mycompany.org:7999/~myusername/example-repository.git

The tilde is not allowed in the regex, rendering the dotfiles plugin v1.2.4 and newer useless for us.

Proposed solution

The validation regex should be changed to allow using "~".

Sadly, the issue is not resolved in 1.3.1 yet. We are getting the message: ERROR: DOTFILES_URI contains invalid characters, which seems to originate from here:

registry/registry/coder/modules/dotfiles/run.sh

Lines 11 to 14 in 6ec506e

	if [[ "$DOTFILES_URI" =~ [^a-zA-Z0-9._/:@-] ]]; then
	echo "ERROR: DOTFILES_URI contains invalid characters" >&2
	exit 1
	fi
