Workspace creation erroring out on special character #

[plank-tools]

Bug description

Some of my branches reference the issue number of the branch. So, my feature branches always start with a "feature/#". When I try to create a workspace on this branch, it fails because it can't find a branch with the url-encoded value of # which is %23. So it fails.

Steps to reproduce

Create a branch in gitlab with the special character # in the middle of the branch name immediately after a /. e.g. feature/#12-abcd
Click the gitpod button in gitlab.

Expected behavior

New workspace should be created

Example repository

No response

Anything else?

I'm encountering this in a v0.10.0 of self-hosted gitlab using gitalb-eks-guide repository.
