@timchilds Product to investigate whether we should update the sections mentioned.

Brave://rewards-internals - Section with heading Wallet info possibly will need to be reviewed so its not confused with anything brave wallet related.

I broke this out into a separate issue, since it's shared between desktop and Android: #24135.
