fix(tray): full width at portrait orientation (#2547)

* docs(tray): docs update and fix guidelines link

Fix incorrect Tray guidelines link that was 404 not found.
Update descriptions in docs to clarify viewport orientation differences.

* fix(tray): full width at portrait

The Tray was not appearing as 100% width in portrait orientation because
of a max-inline-size declaration coming from the .spectrum-Modal class
used with .spectrum-Tray

* fix(tray): whcm use border on correct element to show rounding

Rounded corners were not showing in forced-colors mode, because the
border that was appearing on the nested Dialog element, which has
padding. Moves the high contrast border from that element to the root
Tray element.

* fix(tray): storybook heading text control and unused import

The Storybook "heading" control was previously not usable, due to how
the arg was being passed through to the Dialog. This text string control
will now change the heading.

Replaces an "unused" import for Modal whose CSS is still necessary for
the Tray to render correctly. The unused import would be deleted on
save/fix, resulting in the wrong styles. Replaced the template import
with an import of just the CSS for Modal.

In portrait orientation, a Tray is displayed at the bottom of the screen and takes up the full width of the view. In landscape orientation, it keeps its portrait width, is centered horizontally, and has rounded upper corners.
