feat(input_schema): Add textfield editor support to resource property (#557)

This adds support for:
- `textfield` editor
- and validation keywords (`pattern`, `minLength`, `maxLength`)

for resource properties (fields with `resourceType`).

Based on the outcome of discussion here:
https://apify.slack.com/archives/C081VA3BSCR/p1761036999960109?thread_ts=1760009084.798619&cid=C081VA3BSCR

In the UI this would work out of the box with default editor of
`resourcePicker`.
