update whatsmeow to 20260609091626-4e622162b959

fixes #220

[poVoq]

Are all these seemingly random version bumps and the upgrade of the golang version really required for increasing the version of the Whatsmeow library?

I don't think we can merge this as is.

[ymarkus]

Sorry, my mistake. I tend to run:

go get ...
go mod tidy

Which probably did all the changes. Although the second one only should clean up unneeded dependencies, the repos I used to work on (some time ago) always wanted the tidy step to be run. If you like, I can push only the first step.
The issue with the golang version: https://github.com/tulir/whatsmeow/blob/main/go.mod:

module go.mau.fi/whatsmeow

go 1.25.0

toolchain go1.26.3
[...]

I'm not sure if staying with 1.24.0 even works with this new whatsmeow version.
Also: go 1.24 is out of support so should be phased out anyway...

There are some stable distributions that will stay on 1.24 for a while so we thought about doing a release before bumping the version requirements of that.
