Updates to installation doc with helidon framework notes

[ksurendra]

Added notes mentioning that the dependency jakarta.json:jakarta.json-api:2.0.1 needs to be explicitly added to projects built with other frameworks like Helidon and not only Spring Boot.

Else users will see the same exception at runtime: java.lang.ClassNotFoundException: jakarta.json.spi.JsonProvider.

@ksurendra for my understanding, can you explain what happens in Helidon without the dependency added? Is it forced into a different version as with the Spring plugin? Does it lead to ClassNotFoundException?

@swallez without the dependency users will see a ClassNotFoundException exception at runtime.
To be precise this one: java.lang.ClassNotFoundException: jakarta.json.spi.JsonProvider

Ok, thanks. This looks like the exact same problem as with Spring.

The CLA check still fails. Did you use the same GitHub account when signing it? If yes, I'll reach out to our infra team to understand why it keeps failing.

Thanks. The issue is similar, just wanted to add the wording so it does not look like only "spring" has it.
think I used the same username, anyways re-signed the CLA again.

@ksurendra the docs have been heavily restructured, and I also refactored the installation document to explain this issue in a more framework-independent way while still mentioning Spring Boot and Helidon.

I will therefore close this PR, which has been superseded by PR #265 (and has been published on the website). Thanks for the heads up about Helidon!
