URLSearchParams has() and delete() have new value option

[hamishwillee]

FF115 adds support for new value option to URLSearchParams.has() and delete() methods. This adds the value.

Lots of tracking info in whatwg/url#735 and testing shows:

• this is not yet in chrome.
• Safari says it went into https://developer.apple.com/documentation/safari-technology-preview-release-notes/stp-release-171 which I have marked as preview - is that correct?
• Node added it in 20.2.0 but latest version is 20.0.0 in BCD. Don't know how I work out engines etc to add that entry - is 20.0.0 close enough?
• Deno has PR but not yet merged.

Tests on WPT are:

• https://wpt.live/url/urlsearchparams-delete.any.html
• https://wpt.live/url/urlsearchparams-has.any.html

Upshot, need to confirm that safari and node values are OK to progress this.

Related docs work can be tracked in mdn/content#27172

FYI @queengooborg - some questions above about best versions to use for node etc

FYI, also added spec link to top level for each of the items added by the iterator in the IDL (because these aren't expanded out in spec.

Yes, that should be correct.

• Node added it in 20.2.0 but latest version is 20.0.0 in BCD. Don't know how I work out engines etc to add that entry - is 20.0.0 close enough?

I think we tried to avoid minor and patch nodejs versions in the past. I'm torn. I think either we add them in as needed or we agree we only want major release lines like nodejs has in their own docs. The issue for this discussion is #18777

Generally speaking, we have added minor versions of NodeJS to BCD when needed, and this qualifies. I think that sticking to just major versions of NodeJS is too vague for our consumers.
