Add a way to specify description when creating github-like siblings

[mslw]

This PR adds an optional description parameter to create_sibling_ghlike, and enables it for related (gin / gitea / github / gogs) create-sibling commands. This optional parameter allows specification of repository description (displayed on the project's page), replacing the hardcoded 'some default' (which would still be used the default).

Manually tested for Gin and GitHub.

Fixes #6816

travis errors are due to odd behavior of pip installing older version of datalad-installer

@jwodder -- any idea on why it could have happened all of a sudden?

[jwodder]

@yarikoptic There was an issue in the past hour with PyPI backends being unavailable; see https://status.python.org/#past-incidents. Can you rerun the builds?

[yarikoptic]

Thank you @jwodder ! Finally travis let me to login (can't before earlier today) so I restarted travis build.

Restarted extension test that should be fixed by now.
Ignore the failure on macOS - this is unrelated. Trial to rectify this is #7126
