godoc: add label and button to search bar

To increase accessibility of the search bar,
an aria-label for screen readers and a submit
button was added.

The search field was given the semantically correct
input type and marked required field as hints to UAs
that can use that to provide context to the user.

The placeholder text was restyled for improved contrast.
The javascript for handling placeholders was removed
as it is no longer necessary.

For golang/go#22171
