Add `<0.0.1` compat for all stdlibs outside of julia repo

Churavy, Valentin requested to merge github/fork/sharanry/patch-1 into main

Created by: sharanry

This is remedy with the issue described by @KristofferC on Slack:

For posterity, the bug with the 0.0.0 is as follows:

  1. When testing, Pkg rewrites the stdlib entries to actually be devved, this was needed before https://github.com/JuliaLang/julia/pull/39572 to be able to find stdlibs even if @stdlib was not in the path
  2. Pkg was inconsistent between what version it assigned stdlibs that had no explicit version entry in them. In one place, it gave them version 0.0.0 (https://github.com/JuliaLang/Pkg.jl/blob/e79cb868f7f3c43cdffb5f462a4c21c8ae772eb4/src/Operations.jl#L261) and in another it gave them VERSION (https://github.com/JuliaLang/Pkg.jl/blob/e79cb868f7f3c43cdffb5f462a4c21c8ae772eb4/src/Operations.jl#L507)
  3. So when doing Pkg operations inside a Pkg.test the stdlibs are devved and get version 0.0.0 which are incompatible with the VERSION entries they are assigned to in other places.
