As has already been mentioned by others mostly everything except the name is different.

When it comes to the name, the name isn't anything similar in for example Nordic languages:

Påske (Norwegian, Danish) or påsk (Swedish). Finnish seems to have a similar sounding name. Same with Dutch.

German has Ostern, but I the few others I checked were completely different.

That means even the name similarity only exist in a few languages.

And at the time the Christian celebration of Easter started these languages didn't even exist. The closest language I could find to early Christian history on DeepL was Greek and in Greek the name of Easter seems to be Πάσχ.

With that, this idea should be debunked sufficiently I think.
