Commit 26ff443 made the Gitlab pipeline failing on develop
(while it was not failing in the original PR) due to errors in the
fetcher. This change preserves the new versions, but will give
some time for use to sync our tarball mirror for better reliability

From the release announcement: "This is a special bugfix release ahead of
schedule to address a memory leak that was happening on certain function calls
when using Cython. The memory leak consisted of a small constant amount of bytes
in certain function calls from Cython code. Although in most cases this was not
very noticeable, it was very impactful for long-running applications and certain
usage patterns. Check bpo-46347 for more information."
When you install Spack from a tarball, it will always show an exact
version for Spack itself, even when you don't download a tagged commit:
```
$ wget -q https://github.com/spack/spack/archive/refs/heads/develop.tar.gz
$ tar -xf develop.tar.gz
$ ./spack-develop/bin/spack --version
0.16.2
```
This PR sets the Spack version to `0.18.0.dev0` on develop, following [PEP440](https://github.com/spack/spack/pull/25267#issuecomment-896340234) as
suggested by Adam Stewart.
```
spack (fix/set-dev-version)$ spack --version
0.18.0.dev0 (git 0.17.1-1526-e270464ae0)
spack (fix/set-dev-version)$ mv .git .git_
spack $ spack --version
0.18.0.dev0
```
- [x] Update the release guide
- [x] Add __version__ to spack's __init__.py
- [x] Use PEP 440 canonical version strings
- [x] Make spack --version output [actual version] (git version)
