* FEATURE: Add ignored user list to the User's preference page
## Why?
Part of: https://meta.discourse.org/t/ability-to-ignore-a-user/110254
We want to add list of Ignored users under or along with the muted users preferences section.
This way Users can find and update their list of ignored users.
## UI
## Open questions
Two of many options to represent a list of ignored users is that we can:
1. We can represent the ignored user list as a table with the ability to `un-ignore` but NOT to add new ignored users.
2. We can keep it functioning as the `muted user list` where you can `un-ignore` or `ignore` users.
