Rosetta: "You are currently editing the user" should link to WP.org profile

[SergeyBiryukov]

When adding a new PTE in Rosetta, it displays the following string:

You are currently editing the user <em>username</em>.

For easier user management, username should be a link to the WP.org profile rather than a plain text string.

[SergeyBiryukov]

A couple of use cases:

• When adding a plugin or theme author as PTE for their project in their native language, it would be handy to be able to view the author's other plugins or themes and maybe add them as a PTE for those projects too.
• When adding someone as a PTE, GTEs often take a look at the user's activity on WP.org in general, which might have an effect on the decision.

Rosetta Roles: Link the username of the current user on edit page to w.org profile.

Props SergeyBiryukov.
Fixes #2209.

edit-cross-locale-pte.php was added in the meantime in [4929], needs a similar change: meta-2209.2.patch​.

[SergeyBiryukov]

Just realized we could add the link without changing the existing string, see meta-2209.3.patch​.

meta-2209.4.patch​ also removes <em> tags, as we don't display profile links in italics anywhere else.

Rosetta Roles: Remove recently introduced markup from pre-existing translated string and remove unnecessary <em>.
