Issue:
Easter monday in Switzerland's Canton of Valais instead of Vaud
### Affected country

Switzerland

### Affected public holiday

Easter monday

### Source of the information

https://en.wikipedia.org/wiki/Public_holidays_in_Switzerland

### More information

PR #680 has removed Easter Monday from `<SubConfigurations hierarchy="vd" description="Vaud">` and added it to `<SubConfigurations hierarchy="vs" description="Valais">`, which seems wrong to me: #679 cites https://en.wikipedia.org/wiki/Public_holidays_in_Switzerland, which lists `VS` as the only canton that does not observe Easter Monday, and I see the same on https://de.wikipedia.org/wiki/Feiertage_in_der_Schweiz.

https://www.valais4you.ch/de/wallis-in-kuerze/lebensart/feiertage contains the information:
> Tage vor oder nach den grossen christlichen Feiertagen wie Karfreitag, Ostermontag und Pfingstmontag sowie der 2. Weihnachtstag sind im Wallis offiziell keine Feiertage, werden aber je nach Arbeitgeber als arbeitsfreie Tage gewährt.
