added jakarta namespace

[PeJetuz]

@yegor256
Hi!
Please review, I also create PR for jcabi-parent.
I'm not really clear on whether I should add a dependency to the parent or whether it should only be in takes.
I also want to update the xml to the jakarta namespace.
takes issue 1307

@yegor256 I updated the XML to the Jakarta namespace. Please review.
Thanks!

@PeJetuz maven doesn't build

[PeJetuz]

@yegor256 Sorry, it's mine failed. I should have tested the build on jdk 11.
The artifact "jakarta.ws.rs:jakarta.ws.rs-api:4.0.0" is not compatible with JDK 11, only with 17 and later.
Jakarta EE 11:
This specification requires that containers support execution in a Java™ runtime environment, as defined by the Java Platform, Standard Edition specification, v17 or later (Java SE 17 or later).
I rolled back the version of this artifact to 3.1.0. Should I also create a new PR for jcabi-parent to downgrade this artifact?

@yegor256 Is it possible to run the build again?
Thanks!
