fix(admin): use field-generic wording for details/error prop docs (2026-01)

[sordaz00]

Backport of #4662 to 2026-01.

What

The shared FieldDetailsProps.details and FieldErrorProps.error JSDoc in src/surfaces/admin/components.d.ts was written for checkbox ("displayed below the checkbox", "what checking the box means"). Both interfaces are inherited by every Admin and App Home form component, so the copy renders on non-checkbox reference pages where it reads incorrectly.

Reported via shopify.dev CSAT feedback. Tracked in shop/issues-learn#2959.

Why this version

admin_extensions docs are published per API version on shopify.dev, so each maintained version needs the fix independently. Verified against the live data in World — db/data/docs/templated_apis/admin_extensions/2026-01 still carries the checkbox wording today.

(app_home is published unversioned, so it is fixed by whichever branch syncs last; it is updated here too for consistency within the branch.)

Change

Two JSDoc blocks in components.d.ts, plus the generated docs data: 2 files, 64 replacements total.

Note: this version's generator does not emit the interface source blocks, so only the flattened description strings are present — 31 per generated file rather than 40.

The generated JSON was patched textually rather than by running yarn docs:admin, because the generator copies these strings verbatim. Every occurrence was matched against a known literal — the patch fails loudly on any unrecognized form — all files re-parse as valid JSON, and no residual checkbox wording remains under src/ or docs/.
