Except `dao.bond.bondedRoleType.ROCKET_CHAT_ADMIN` which refers to an
unused role, every other instance of `keybase` has been contextually
updated to Matrix (bisq.chat); functions to display moderator name
and profile address on keybase have been updated to work with Matrix
usernames and urls.
Kept translated resources in original state as per jmacxx suggestion.
Renamed the issue_template.md to bug-report.md to adhere to
Github's guidelines.
I added semanticly relevant front matter to the issue_template.md
so that it explicit that it should be reserved for reporting bugs
or unintentional behaviours from the software.
