Panic when compiled on go 1.22

[zemanlx]

wsl works well when used with go 1.21

$ docker run -it --rm -v $PWD:/code -w /code golang:1.21 bash -c "go install github.com/bombsimon/wsl/v4/cmd...@master && wsl --fix ."
go: downloading github.com/bombsimon/wsl/v4 v4.2.0
go: downloading golang.org/x/tools v0.6.0
go: downloading golang.org/x/sys v0.5.0
go: downloading golang.org/x/mod v0.8.0

but panic when compiled on go 1.22

I have run it on the master of this repo.

Thanks for this! Seems like a simple bump of dependencies doing the trick, updated them and it now works with Go 1.22 (also tested Go 1.21 and Go 1.20).

The install instructions and your command mentions master so it should already work but I'll draft a new release so you can do go install github.com/bombsimon/wsl/v4

[bombsimon]

Should be released under v4.2.1
