Syntaxic differences in version numbers are kept accross updates #6754
Description
Very minor issue and should make very little functional difference (although i might be able to find one, e.g. extract some extra-files or things like that), but it is surprising nonetheless
### <pkg:some-pkg.00>
opam-version: "2.0"
### opam install --show some-pkg
[...]
* install some-pkg.00
[...]
### mv REPO/packages/some-pkg/some-pkg.00 REPO/packages/some-pkg/some-pkg.0
### opam update
### opam install --show some-pkg
[...]
* install some-pkg.00
[...]
This is a minor regression compared to 2.4 due to #6614
