OSGi / Spifly Provider for jakarta.ws.rs.ext.RuntimeDelegate cannot be found

I have an OSGI environment with jersey-common 3.1.9, jakarta.ws.rs 3.1.0 and spifly 1.3.7

On startup console says
```
Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: Provider for jakarta.ws.rs.ext.RuntimeDelegate cannot be found

`jakarta.ws.rs.ext.RuntimeDelegate` is available within `jersey-common` and the `/META-INF/services/jakarta.ws.rs.ext.RuntimeDelegate` file exists.

It is, however, NOT being picked up by spifly. This is due to `/META-INF/MANIFEST.MF` not containing the required `Require-Capability` and `Provide-Capability` entries. See https://aries.apache.org/documentation/modules/spi-fly.html#specconf for details.

For example:

`logback-classic` correctly writes this info to `MANIFEST-MF` in https://github.com/qos-ch/logback/blob/5610c96b4d705a4fe6ded9c42d4f47cb92bbbd95/logback-classic/pom.xml#L343

while `jersey-common` does not do so in https://github.com/eclipse-ee4j/jersey/blob/d9658aa3064236abf1280f16e1705454e5d0b599/core-common/pom.xml#L150C25-L150C120

So adding the resp. extension should make OSGI Spifly pick up the required RuntimeDelegate and make it run, while it should not change behaviour for non-osgi uses of the bundle.
