docs: add v8 beta blog post

[JoshuaKGoldberg]

PR Checklist

• Addresses an existing open issue: fixes Docs: Add blog post announcing v8 beta #9021
• That issue was marked as accepting prs
• Steps in Contributing were taken

Overview

Adds a preliminary blog post announcing the v8 beta, including:

• A brief intro on the project and the leadup to v8
• Steps to set it up (mostly pointing to getting started & configuration docs)
• Lists of user-facing changes, especially breaking changes
• Lists of developer-facing changes, especially breaking changes
• Acknowledgements

As with v6's #6515, uses ⌛ to indicate parts that aren't yet merged in.

Sending for review now though I believe it should be blocked on a couple of other items, commented inline. I think it's ready for review in the meantime so we can ship it ASAP once those items are resolved.

I think we should consider project service stability & resolved naming a big enough feature to block releasing this blog post. #9004

[JoshuaKGoldberg]

Hmm, now that all the planned new features for it are in (allowDefaultProjectForFiles, defaultProject, maximumDefaultProjectFileMatchCount_THIS_WILL_SLOW_DOWN_LINTING) are in, we could give a big caveat/notice here that it's all available under the old EXPERIMENTAL_useProjectService name.

Had a read through this (and checked for typos) and looks good - can't wait! :D

This is currently rendered as:

… which is a bit confusing. Either both comments should display verbatim, or both should be rendered like a diff. I saw below that the latter can be achieved like this:

Suggested change

	// Remove this line
	project: true,
	// Add line
	projectService: true,
	tsconfigRootDir: import.meta.dirname,
	// Remove this line
	project: true,
	// Added lines start
	projectService: true,
	tsconfigRootDir: import.meta.dirname,
	// Added lines end

Why is it slow? I don't quite get it from the context; maybe that can be improved somehow.
