[Blog post] Introducing the 2 + 2 + 2 Java support plan

[basil]

External user-facing communication about the 2 + 2 + 2 Java support plan, including the relevant upcoming dates as well as a practical discussion about the tradeoffs involved in making this decision.

Testing done

Viewed https://github.com/basil/jenkins.io/blob/java-blog-post/content/blog/2023/11/2023-11-06-introducing-2-2-2-java-support-plan.adoc and confirmed the content was readable and the dates were accurate.

Small optional suggestion, great blog post!

The Gantt charts aren't being rendered, so once the content is finalized I will convert them to rendered images. I'll wait until after the content is finalized to ensure that I only have to do this a single time. If anyone has any better ideas about how to make the static site generator render the Gantt charts, let me know.

Thanks.

I added an opengraph image in 79ced5f so that the list of pages would have a picture to describe the blog post. The picture was created from the Jenkins social media covers slide deck

I looked into trying to have Asciidoctor render the Gantt charts via asciidoctor-diagram, but this wasn't practical. asciidoctor-diagram requires mermaid-cli to be installed when it is running, but that is a JavaScript (not Ruby) package, and our build currently has separate stages and separate Docker environments for JavaScript and Ruby, so each environment is unavailable from the other. And this does keep the build nice and simple by allowing us to use unmodified upstream Docker images, in contrast to having to maintain an omnibus build environment ourselves with every possible tool installed.

So given the above, I ran asciidoctor-diagram locally with its SVG backend to generate rendered SVG versions of the Gantt charts, which I have included in this PR. While not as nice as being able to automatically render Mermaid markup, this is more practical because it avoids having to change our build significantly.

I have checked the preview site and confirmed the rendered SVG Gantt charts are displaying correctly.

This is great, thanks very much @basil.

I noted one small suggestion regarding a line, but outside of that everything looks good to me and the charts are rendering nicely.

Suggested change

	This plan balances the needs of large scale users for predictability and stability
	with the needs of early adopters and developers
	to improve and simplify Jenkins with the latest Java capabilities
	and to reduce the maintenance overhead associated with a large build and test matrix.

Small suggestion to add some punctuation for sentence structure/avoiding a run on sentence.

[basil]

A run-on sentence occurs when two independent clauses run together without proper punctuation or appropriate conjunctions. A clause requires both a subject and a verb. This sentence has only one subject: "plan". The only other nouns in this sentence are functioning as direct objects or objects of prepositions. So there is no run-on sentence here.

This plan balances the needs of A for B with the needs of C to D and to E.

A = large scale users
B = predictability and stability
C = early adopters and developers
D = improve and simplify Jenkins with the latest Java capabilities
E = reduce the maintenance overhead associated with a large build and test matrix

Adopting your suggestion would result in the structure

This plan balances the needs of A for B, with the needs of C, to D and to E.

This places commas before two prepositions, which is grammatically incorrect for the reasons given in https://thecriticalreader.com/no-comma-before-or-after-a-preposition/
