Could one gain a significant advantage using Julia in Linux running within WSL2 compared to the Windows version?

Package instantiation. 239 dependencies, always starting from blank slate (no depot).

```julia
Julia Version 1.9.0
Commit 8e63055292 (2023-05-07 11:25 UTC)
Platform Info:
  OS: Windows (x86_64-w64-mingw32)
  CPU: 8 × Intel(R) Core(TM) i7-1065G7 CPU @ 1.30GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-14.0.6 (ORCJIT, icelake-client)
  Threads: 1 on 8 virtual cores
Environment:
  JULIA_IMAGE_THREADS = 1

```

Platform Info:
  OS: Linux (x86_64-linux-gnu)
  CPU: 8 × Intel(R) Core(TM) i7-1065G7 CPU @ 1.30GHz
  WORD_SIZE: 64

```

Windows 11 measurements: 452, 521, 505 seconds, mean 492 seconds.  
WSL2 measurements: 411, 392, 424 seconds, mean 409 seconds.

Conclusion: It is possible to reduce the instantiation time around 20% with WSL2.

This guy takes a while to compile. Differences in precompilation are small, but favorable to Windows

```julia
# Win
