Configuration manual missing non-default variants for `hover.memoryLayout.*` configs

Hello, partial issue, partial question.

When configuring my LSP, I noticed that the below configurations show their default values, but do not show other valid values (variants).

I believe there are 3 configurations in the memoryLayout category that are guilty of this.

The config assumes the end user is familiar with common representations of memory. I am sure most are, but maybe explicitness is preferred

Config items without information on variants.

• memoryLayout.alignment (Default "Hexadecimal")
• memoryLayout.size (Default "Both")
• memoryLayout.offset (Default "Hexadecimal")

These configs were deemed reasonable around #14918.
#14929 is when they were actually implemented. Interestingly, the latter of those PRs include a json file showing the variants for VSCode settings. Maybe it was forgotten for the reference on the website

If a PR is welcome, I can try to poke at it, I'm very unfamiliar with RA internals. Don't mind learning something new though. If people feel it is not worth the time, feel free to close

AFAICT - Currently, you must search the repo to learn of the possible values. That could feel annoying for a new user to do

Start with the three linked rust-analyzer manual entries for memoryLayout.alignment, memoryLayout.size, and memoryLayout.offset, then inspect the JSON file in PR #14929 for the valid variants. Update the reference documentation so each configuration lists its non-default values, and verify the rendered manual entries show them.
