Support jakarta Nullability annotations

https://youtrack.jetbrains.com/issue/KT-54205/Support-jakarta-Nullability-annotations

Many users are migrating from javax.* to jakarta.* as a result of spring's javax EE migration.

If we are careless at this time and migrate javax.annotation.Nullable to jakarta.annotation.Nullable as well, we will have a problem. Because kotlin does not support it.

It would be great if kotlin would support it as well.

Sorry for the delay. I've committed the part you suggested.

Hi there, thanks for your work! In which target branch (1.9.x, 1.8.x) is this going to land?

[tekener]

Hi, at lease 2.x please. With Spring Boot moving to jakarta there is really a need for this feature.

[be-hase]

Hi, 1.9 and 2.x would be nice.
