fix: reset form inputs by default when using remote form functions

[dummdidumm]

Fixes a weird inconsistency: Full page reloads clear the form fields, but when using JS to enhance it (which happens by default) it's no longer resetting. This fixes that. If you enhance you still can decide which way you want to go.

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.
