[feature] access docs for devel branch

[timotheecour]

something like: https://dlang.org/phobos-prerelease/std_algorithm.html (which even has a way to select the tag/branch eg 2.080 instead of master, although at least allowing to serve docs from tip of devel branch, say updated after every PR would be already a big improvement)

EDIT: this is now implemented as of nim-lang/Nim#8992

• [RFC] regarding committing docs and auto-updating documentation website · Issue #25 · citycide/glob
• https://github.com/kaushalmodi/nim-nightly-docs
• Visit https://nim-lang.github.io/Nim/ for the latest docs built from the Nim devel branch.

=> nim-lang/Nim#8423 after this PR, we can work around this by building docs locally (more flexible since allows building docs for arbitrary commits/branches, but maybe still worth publishing docs for devel branch regardless for ease of use for ppl who don't want to build docs locally yet see latest devel docs

[timotheecour]

I believe git hooks could be used for that purpose, ie update docs whenever devel is updated with a new commit, see https://www.digitalocean.com/community/tutorials/how-to-use-git-hooks-to-automate-development-and-deployment-tasks

+1 from me. I much prefer to use the online docs more than the locally generated ones, and it would be nice to have the ones from devel up there.

thanks @kaushalmodi for implementing this! closing
