Before this change, we'd get:
$ guix refresh gedit
updating from version 40.1 to version 43.alpha...
This is because the new GNOME version scheme introduced in 2021 with GNOME 40
was not treated correctly. Also, no longer ignore odd numbered minor
versions, as this appears to be a declining practice in GNOME.
* guix/import/gnome.scm (latest-gnome-release)
<pre-release-text?>: New predicate.
<even-minor-version?>: Rename to...
<release-version?>: ...this. Return #f in case the version corresponds to a
development release.
* guix/import/gnome.scm (latest-gnome-release): Adjust accordingly.
Reported by Maxim Cournoyer.
This is a followup to 61b63e7fa7.
* guix/import/gnome.scm (latest-gnome-release)[even-minor-version?]:
Reject VERSION is the minor or micro part is not an integer.
That way, "guix refresh gnome-keyring" will properly return "42.1"
instead of "42.0".
Reported by Maxim Cournoyer.
* guix/import/gnome.scm (latest-gnome-release)[even-minor-version?]:
Tweak for GNOME applications.
* guix/import/texlive.scm (tlpdb->package): Add VERSION argument; include
explicit version field in output.

I missed this remark from the review when pushing the last change.
* guix/import/pypi.scm(python->package-name): Replace the trailing '#t'-case
by a 'else'.
Trytond modules are Python packages, and treated like this in guix. Anyhow,
since they are add-ons for the “Trytond“ application, their guix package name
do not get the "python-" prefix like other Python modules, (see also
https://issues.guix.gnu.org/46057#1). This change disables adding the
"python-" prefix to the guix package name for Trytond modules when importing
and updating, thus inhibiting irritating messages like in this example:
$ guix refresh -u trytond-party
…
trytond-party: consider adding this propagated input: python-trytond-country
trytond-party: consider removing this propagated input: trytond-country
Handling this special case seems appropriate since (as of now) there are
about 165 packages for Trytond and the number is growing.
* guix/import/pypi.scm(python->package-name): Don't add "python-" prefix for
trytond packages.
'egg-source-url' did not return the URL, but the quoted expression. This did
break the updater, which expects the URL as a string.
* guix/import/egg.scm(egg-source-url): Remove.
(egg->guix-package)[egg-content]: Use quoted expression directly.
(latest-release): Call egg-uri instead of egg-source-url.
This effects packages hosted at github with source-uri like
…/releases/download/REPO-VERSION/REPO-VERSION.EXT.
E.g. ‘guix refresh udisks’ would fail to find the new release of ‘udisks’
before this change.

Previously, 'guix refresh' would literally crash when the rate limit was
reached due to the call to 'error'. With this change, the updater
notices when the rate limit is reached and it turns itself into a no-op
until the rate limit has been reset.
When running "guix refresh" (with no arguments), the 'github' updater
gets used until the rate limit has been reached, after which "guix
refresh" automatically picks up the next valid updater, typically
'generic-git'.
