cabal doesn't reconfigure ghc-pkg when binary on PATH changes

[fendor]

Describe the bug

Perhaps related to #11373

cabal-3.16.1.0 doesn't reconfigure ghc-pkg when I switch the ghc version on PATH.

To Reproduce
Steps to reproduce the behaviour:

> cabal-3.16.1.0 get text-2.1.3
> cd text-2.1.3
> ghcup install ghc --set 9.10.3
> cabal-3.16.1.0 path
> ghcup install ghc --set 9.12.2
> cabal-3.16.1.0 path
Error: [Cabal-4000]
Version mismatch between ghc and ghc-pkg: C:\ghcup\bin\ghc.exe is version 9.10.3 C:\ghcup\bin\ghc-pkg.exe is version 9.12.2

Expected behavior

Should correctly reconfigure and show the output of cabal path regardless. Works fine on cabal-3.14.2.0 on windows.

System information

• Windows (uncovered by HLS CI)
  • I would guess this is reproducible on linux as well
• cabal-3.16.1.0
• ghc versions 9.12.2 and 9.10.3 but probably irrelevant

Workaround

Remove dist-newstyle directory.

#10731 looks like it might be relevant. (I don't promise there aren't others, and in fact I was looking for a different PR that I vaguely recall but didn't spot on this quick check.)
