[SupportedBrowsers] Small update

[contribucious]

This:

[~]

• switches the order of priority "Fennec,Fenix" to "Fenix,Fennec" for org.torproject.torbrowser (see their blog post and annex 1 below).

[+]

• adds a precision about the non-presence in this list of com.android.htmlviewer (entry added by @stevenlele in this PR).

[-]

• removes the deprecated org.ungoogled.chromium as planned here;
• removes unnecessary precision about the version regarding some entries added by @stevenlele (for the sake of clarity, let's only add this information in the source code itself when more than one resource-id is present — typical case: current and legacy value).
