feat: ORA autosave enhancements (#1981)

* feat: Update autosaving text

* refactor: reduce auto save timer to 2s

* feat: allow specifying icon on autosave status section

* refactor: update default save text

* feat: update icon styling for autosave

* feat: remove save button

* feat: allow autosave to recover from save error

Previously, we wouldn't autosave if we had previously encountered an
error because the user could manually retry. On removing the save
button, it became necessary to allow the ORA to retry saving. This logic
mostly is around debouncing error banners so the user can continue to
edit a response without unnecessary defocusing or visual noise.

* feat: update error messaging

* feat: update template text to explain auto saving

* feat: remove redundant submission tip section

* feat: add line between files and text sections

If *both* are present, helps to visually distinguish text and files
sections.

* feat: remove extra padding from file chose button

* feat: more consistent padding / margins

* style: remove bad / unused scss rules

* fix: fix scss typos

* style: fix linter warning for scss

Linter was warning that -webkit--appearance should also have the
appearance style rule alongside it.

* feat: move supported file types to its own line

Helps avoid weird wrapping issues when supported type list is too long.

* chore: build static files

* chore: update translations

* refactor: move hr inside of team upload template

Preserves existing test behavior while preserving updated line styling.

* test: update tests

* refactor: remove save button code

* chore: bump ORA to 5.1.0 from 5.0.4
