First implementation of the @@personal-information is done. Updated branch with current main to resolve conflicts. README.md check failure is unrelated as far as I see.

Rough edges, which were not blockers, just flagging them:

• I've added "personal information" to the dev header next to login/logout. I've also parked the idea using the left toolbar with Plug, since it should go under some sort of user settings menu eventually.
• Currently Save/Cancel live inside the form because the toolbar Plug button's onPress/onSubmit never fired.
• The form is rendered schema based. However there is no email/url widgets registered, so for now everything renders as plain TextField.
• The portrait field is also renders as a text box, thus it is skipped on "Save".
• Change-Password link has been created with reset-password route from PR #48 Add password reset flow to CMS UI #109. I have not bumped into any change-password route, so put it there as a reminder - see also [CMSUI] - User preferences route #47 (comment).
• Entry point is the header, the real home is a future user/avatar menu. I assume it will have its own issue.
• The language/timezone fields are out of scope. See discussion about the issues with @userschema and write-only backend - see also [CMSUI] - User preferences route #47 (comment). That is until plone.restapi provides an updated schema with IPersonalPreferences fields and read path for the same fields - TBD.
• I was unable to confirm translations. I tried extending supportedLanguages, which is hardcoded to ['en'], but had no effect. Probably I'm missing something.
• For accepntance tests I have used the plone.app.testing's user test_user_1_. I've seeded it with data for the tests. That might be something to move into the tooling/playwright, to make it reusable.
• Minimal a11y and alerts, since no central Form feedback.
