Bug 35186: Remove unnecessary html tags from PASSWORD notices
In HTML notices we don't need to explicitly use <html></html>.
This removes them from the 2 notices using them:
* PASSWORD_RESET
* STAFF_PASSWORD_RESET
To test:
* Apply patch
* Make sure your Koha can send email (set up SMTP server, KohaAdminLibraryAddress)
* Make sure your patron has an email set
* In patron account, use "More > Send password reset"
* Log out
* In the OPAC, request password reset ("forgot your password?")
* Verify both notices appear nicely formatted (line breaks, bold, etc.)
