Bump guice to 7.0 and replace deprecated javax inject with jakarta inject

The aim

With java 9 the javax.* namespace moved to jakarta.* (https://jakarta.ee/blogs/javax-jakartaee-namespace-ecosystem-progress/).
Since restlet minimum java version is now 17, we should also move to jakarta.*

The solution

Replace javax.* with jakarta.* and bump guice to 7.0.0

[Tembrel]

Note that this might break the org.restlet.ext.guice extension, which depends on javax.inject. (I am the author of that extension.) It could be that simply replacing javax.inject with jakarta.inject, as has been done here, will work, but I have no way of testing that, since I am stuck on Restlet 2.5 and Java 8 for the foreseeable future, for narrow technical reasons.

I have indicated elsewhere that I would be fine with removing the "Guice" extension entirely in 2.6, since I think the very small amount of code needed to make ServerResources injectable doesn't warrant an entire extension.

But some people might reasonably expect to continue using it. 😉

Thanks @notz Have you been able to test the code to ensure it is working as @Tembrel isn't able to do so? Also, could you send us the signed JCA? See document in wiki. https://github.com/restlet/restlet-framework-java/wiki/Contribute

@Tembrel I think we should deprecate the Guice extension in 2.6 for removal in 2.7 per your guidance. We can always revisit this for version 3.0 and reconsider in 2.7 based on community feedback

@Tembrel i already did this port of the guice extension earlier to guice 7.0 and it works perfectly
I did a part of the port the team is doing now on 2.6 earlier and we are running on acceptance for a while now without any problems; Java 21, Jetty 12, GWT 2.12.1, jakarta.*, Guice 7.0.0

@jlouvel We use that changes, along with Java 21 and Guice 7.0.0, also for some time now.

But it's ok for use to remove the extension. Since it's really very simple. I think, I have already signed the jca a long time ago, but it's no problem to do it again. Where should I send the signed jca?

Thanks @notz for confirming the changes are working for you, please send it to [email protected].
