Form methods are case sensitive

[adobley]

Actual behavior

When configuring the form method the method type is case sensitive. This was surprising and led to some confusion. When configuring the form as below the form sends a POST instead of a GET.

<.form for={@form} method="GET" action={~"/my-route"}>

The docs do mention If the method is not get nor post but it isn't clear that this is case sensitive.

Expected behavior

method="GET" should cause the form to submit a GET request.

Fixes

• We'd be happy to submit a docs fix PR that makes this clear it is case-sensitive or,
• We could make a PR that always downcases the method when it is pulled out of the config on the form component
