Convert webkitdirectory to standard

[BaconMan1168]

Description

Add a note to the <input type="file"> reference page's "Non-standard attributes" section explaining that webkitdirectory is in the process of being standardized.

Motivation

The issue reported that the page doesn't mention webkitdirectory is being standardized. I confirmed the current spec status before editing:

• The WICG File and Directory Entries API spec, which defines webkitdirectory, explicitly states it "is not a W3C Standard nor is it on the W3C Standards Track" — it's a WICG Community Group draft, not a full standard.
• browser-compat-data's entry for html/elements/input.json's webkitdirectory still has "standard_track": false.
• The WHATWG HTML Standard does not define webkitdirectory.

Since it isn't yet part of a full WHATWG/W3C standard, I kept it in the "Non-standard attributes" section (rather than moving it out) and added a note pointing to the WICG spec that is standardizing it, so readers get the "it's on track to become standard" context the issue asked for without an inaccurate "this is now standard" claim.

I also checked the sibling HTMLInputElement.webkitdirectory property page — it doesn't make any explicit standard/non-standard text claim (its Specifications/Compat sections are auto-generated from BCD), so it's already consistent and didn't need a change.

Additional details

• WICG entries-api spec
• webkitdirectory BCD entry (standard_track: false)

It is standardized. Please make it be documented as a standard attribute.

This also applies to the <input> page.

Just saw that BCD says it's non-standard. I think you should get that fixed first because right now it's inconsistent with https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/webkitdirectory.

Traced the inconsistency down: browser-compat-data has two entries for this feature with mismatched status. api.HTMLInputElement.webkitdirectory already has standard_track: true and a spec_url pointing to the File and Directory Entries API definition, but html.elements.input.webkitdirectory had standard_track: false with no spec_url. Opened mdn/browser-compat-data#30413 to align the two.

Pushed a commit here that moves webkitdirectory out of the "Non-standard attributes" sections on this page and on the <input> page, into the regular attribute lists, so both pages match once the BCD fix lands.

Thank you, I think we can proceed regardless of the BCD status. Why was the BCD PR converted to draft?
