SI Tor Browser security level instructions are outdated

[eaon]

Description

When visiting the source interface with Tor Browser while JavaScript is enabled, a warning is displayed that includes a dialog with instructions of how to change it to "Safest". This dialog still references old language not used by recent versions of Tor Browser.

Expected Behavior

The dialog showing up to date language to properly guide sources

Actual Behavior

Comments

When Change is selected, the TB opens up a new tab and shows the Security Level section of the browser preferences. I think we should probably indicate that the change happens in a new context. Maybe something along the lines of:

2. Select Change to open Security Level preferences
3. Select Safest and close preferences

[eloquence]

I would say:

2. Click Change to open Security Level preferences
3. Select Safest and close the preferences tab

Otherwise SGTM. ("Click" instead of "Select" because there is no selection of multiple options here.)
