[SPARK-49964][BUILD] Remove ws-rs-api package

### What changes were proposed in this pull request?

- To Remove the dependency of `javax.ws.rs.ws-rs-api` as it's no longer required.

Prior discussion can be found on:
 - #41340
 - #45154

### Why are the changes needed?
In the past, the codebase used to have a few .scala classes referencing and using the `ws-rs-api`, such as b7fdc23#diff-9c5fb3d1b7e3b0f54bc5c4182965c4fe1f9023d449017cece3005d3f90e8e4d8R624-R627

However as the time passed by, all usages of `ws-rs-api` are either got removed / refactored. Hence there is no need to have it import on root POM as now and we can always re-introduce it later, if the usage can be justified again.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
Unit-test, to make sure the codebase is not impacted by the removal of the dependency.

### Was this patch authored or co-authored using generative AI tooling?
No

Closes #48461 from hiufung-kwok/ft-hf-SPARK-49963-remove-ws-rs-api.
