"pwsh not found in %PATH%" on Windows + MacOS

# Issue
Powershell can be installed on Windows or MacOS and a script is used from a custom `platform.txt` but the `pwsh` fails to be found even though it can be ran from any `cmd` windows or terminal

# Reproducer
Winows Powershell 7 can be obtained from the store here https://www.microsoft.com/store/productId/9MZ1SNWT0N5D
Then in Platform.txt add:
`recipe.hooks.sketch.prebuild.01.pattern=pwsh`

# Diagnostics
On windows `pwsh` is installed to `C:\Program Files\WindowsApps\Microsoft.PowerShell_7.1.3.0_x64__8wekyb3d8bbwe` which is not part of 'path' however there is some sort of symlink (alias?) that is used
MacOs similar occurrence but a symlink exists to `/usr/local/microsoft/powershell/7` but Ardunio IDE doens't seem to follow links.

# Workaround
Pretty hacky and destined to fail after an update but on Windows adding the `C:\Program Files\WindowsApps\Microsoft.PowerShell_7.1.3.0_x64__8wekyb3d8bbwe` to PATH environment is a workaround, we tried to repeat it on MacOS but modifying PATH was not as easy.

# Conclusion
The Arduino IDE is not following/supporting Symlinks in some manner and/or launching in some 'custom' manner that does not reproduce what a `cmd` or `terminal` prompt can launch.

Start with the custom platform.txt hook recipe.hooks.sketch.prebuild.01.pattern=pwsh and reproduce it on Windows and macOS. Compare how the IDE-launched hook resolves pwsh with the behavior from cmd or a terminal; done means the installed PowerShell command, including the reported symlink or alias, is found without the PATH workaround.
