Enable Translate feature by default

[atuchin-m]

The feature is nearly to be rolled to 100% of users.
brave/brave-variations#355

The feature should be enabled by default in the code and the griffin experiment should be finished.

@atuchin-m could you provide a test plan for QA to use if manual QA is required here? if not, we should have this labeled as QA/No. Thanks!

[atuchin-m]

@LaurenWags IMHO we need only sanity check that the feature is enabled despite the Griffin config.

@atuchin-m is the following sufficient?

1. do a new profile (don't restart, so griffin isn't pulled)
2. visit a site like interia.pl
3. confirm we're offered Brave's Translation service not Google's

[atuchin-m]

Yes, that's enough.

[LaurenWags]

perfect, thanks for confirming @atuchin-m!

Confirmed on a clean profile (without restart, so no griffin seed pulled), that Brave's translate service was offered, not the Google extension:
