Spike: Submit button type

[ArakTaiRoth]

Info

Currently when people use the submit button type it currently creates that type of button, but it doesn't actually function as a submit button type. What this means is that forms cannot be submitted a normal way by hitting enter within an input area. This isn't as big of a deal for large forms, but for things like search forms with only one input and a button, this completely changes how people will normally interact with the form.

Acceptance Criteria:

1. Determine if there's anything we can do to make the submit button type actually function as it should.

There is a story to deprecate the submit button type - #1321 - If something comes out of this Spike, then this story might be modified to make those changes instead of deprecating it.

This is a link to a description of the issue and why it doesn't currently work for us.

@ArakTaiRoth Do you think there is some functionality is Svelte 4 or 5 that might help us enable this? If so, would it make sense to revisit once we are able to upgrade?

Wait on this until we have upgraded Svelte, after we have moved to the Website.
