new d44817b chore: Rewrite to scala3 syntax (#308)
d44817b is described below
commit d44817bbb9dfd97eb85ab0b1052e958cbf4c39b0
Author: He-Pin(kerr) <[email protected]>

chore: Rewrite to scala3 syntax (#308)
Motivation:
Let Scala 3 Community build compile pekko-persistence-dynamodb.
Modification:
Update .scalafmt.conf dialect to scala213source3 and enable
scala3 syntax rewrite rules, then reformat all sources.
Result:
Wildcard types use ? syntax (e.g. Class[?] instead of Class[_]).
Tests:
Not run - formatting only
