FormData does not include submit button value and name

[peerreynders]

Describe the bug

FormData is captured without including name/value of the submit button:

Defect location: In the vicinity of

solid-router/src/data/events.ts

Line 114 in 9755b8d

const data = new FormData(evt.target as HTMLFormElement);

Compare to previous implementation: https://github.com/solidjs/solid-start/blob/443955f7fe677f558f613d80bafd78b570c136f6/packages/start/data/Form.tsx#L283-L287

Supporting background: FormData doesn't include value of buttons

Clicking on the Log In button when client side JS is enabled produces on the server side:

(email, kody@example.com)
(password, twixrox)

Clicking on the Log In button when client side JS is disabled produces on the server side:

(email, kody@example.com)
(password, twixrox)
(kind, login)

i.e. the JS enabled version is lacking the "kind", "login" name/value pair from the (clicked) button element inside the <form>.

Thanks never noticed that previously but then again we have to thank Remix for a lot of the research there.
