Remove references to Gitpod

[rebkwok]

Update: we now want to remove Gitpod entirely.

@brianmackenna pointed out that the getting started guide in the docs implies that gitpod is the preferred method of running OpenSAFELY. It currently is not - at least not for committed users. If we continue to support gitpod we may want to consider:

• stating clearly that approved OpenSAFELY users (as opposed to interested parties just having a look at the tool) should aim to use a local install if possible
• Switching the order of either the introduction to the options, or the tabs (or both) so that the local install options are shown first

Makes sense!

Our Gitpod config no longer works. Example error messages are:

We're now using Github Codespaces to fulfil the same need, which we have documented here:
https://docs.opensafely.org/github-codespaces/

We should expunge all references to Gitpod from the docs and, where appropriate, replace them with references to Codespaces.

Relatedly, I'd add that:

• the Getting Started guide might actually want to put "run in Codespaces" as the primary way of seeing how things work (which is what the ehrQL tutorial does), and making "install on your own machine" a further step, given the complications we've seen for local installs ¹
• a fair chunk of the initial ehrQL tutorial likely overlaps with the Getting Started guide, and we may want to consolidate these somehow; it may be as simple as pointing users to the ehrQL tutorial as the first thing to work through

This landed on the pipeline board, but we're pretty sure it's a data team task, do shout if we've misunderstood something!

This came up again today: https://bennettoxford.slack.com/archives/C63UXGB8E/p1700731771623999?thread_ts=1698849577.197769&cid=C63UXGB8E so I think it should be a reasonable priority in the near future.
