Submitter Checklist:

• Submitted a ticket for my issue if one did not already exist.
• Used Github auto-closing keywords in the commit message.

• Ran git rebase -i to squash commits (if needed).
• Tagged reviewers and labelled the pull request as needed.
• Request a security/privacy review as needed. (Ask a Brave employee to help if you cannot access this document.)

Test Plan:

1. Visit some sites
2. Open about:payments
3. Click a trash icon
4. Ensure that the appearing confirmation dialogue, depending on the choice, allows the removal of the site or does nothing.

Reviewer Checklist:

• Request a security/privacy review as needed if one was not already requested.

Tests

• Adequate test coverage exists to prevent regressions
• Tests should be independent and work correctly when run individually or as a suite ref
• New files have MPL2 license header

Two translations added under the name: banSiteConfirmation. Mechanism for creating the confirmation dialogue mimics that shown in the syncTable component. Ref: here

@NejcZdovc seems I royally screwed up the squash ;( I figured just opening up another PR in this case would be cleaner.. We should be good to go :)
