Add gitpod and mamba profiles to the pipeline template

[mahesh-panchal]

Gitpod requires a few additional settings in order to make full use of the resources for workflow testing.
Mamba is increasingly used over conda, and so it makes sense to have a profile for it.

LGTM, both would be useful. Is there docs confirming the size of a gitpod node? 60.GB seems quite large for a ('free'-service!)

There's no docs. It can change at any time to be honest. I use htop to check memory and cpus available
