Delete broken version database entries.

[BillyONeal]

Under normal circumstances, things can't be removed from the version database, because that breaks outstanding references to those versions. However, these entries can't be parsed in the first place which means nobody can be depending on them being there. (Usually this comes from accidentally merging PRs that add multiple versions, such as 8184c5e #31859 )

Usually this comes from accidentally merging PRs that add multiple versions

I guess part of the problem is that vcpkg x-add-version --overwrite-version does not overwrite if the version in manifest is not the same as the version in versions.json.
