a11y: Set textarea name parameter also as aria-label
Summary:
Form elements should have associated labels per https://www.w3.org/WAI/tutorials/forms/labels/
Setting the `name` parameter for a `<textarea>` also as its `aria-label` is clearly more accessible than exposing no hints at all.
Ref T16072
Test Plan:
Go to http://phorge.localhost/D1, inspect comment field (below "Add Action..." dropdown) markup, see additional `aria-label="comment"` for `<textarea>`
Go to http://phorge.localhost/T1, inspect comment field (below "Add Action..." dropdown) markup, see additional `aria-label="comment"` for `<textarea>`
Go to http://phorge.localhost/maniphest/task/edit/1/, inspect Description field markup, see additional `aria-label="description"` for `<textarea>`
Go to http://phorge.localhost/paste/edit/1/, inspect Text field markup, see additional `aria-label="text"` for `<textarea>`
Optionally, run an Accessibility check in Chromium Lighthouse.
