When I click settings-Info, I am redirected to /superset/welcome/, except for the admin account.

### Bug description

The bug is as follows:
1. Click Settings - Info
2. It redirects to the welcome page (https://example.com/superset/welcome/).

If use an account with the admin role, it will be redirected to https://example.com/user_info/ normally.
alpha\gamma does`t work

If I enter https://example.com/users/userinfo/ in the Chrome browser, it will redirect to an old user info page.

### Checklist

- [x] I have searched Superset docs and Slack and didn't find a solution to my problem.
- [x] I have searched the GitHub issue tracker and didn't find a similar bug report.
- [ ] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section.

Reproduce the Settings → Info flow with a regular account and an admin account, comparing the redirects to /superset/welcome/ and /user_info/. Start by tracing the route handling for Settings-Info and the role-based access decision; done means non-admin users reach the current user info page without being sent to the welcome page, while the legacy /users/userinfo/ behavior is addressed as appropriate.
