[BUG] - EditUsers reply messages

[IsoFrieze]

Describe the bug

1. User avatars are not being replaced in the small "replying to" section of a message (User names are being replaced properly here).
2. User names are not being replaced in the small "activity command" section of a message.

To Reproduce

1. Reply to a message from someone who has a custom avatar set. The smaller icon that appears above your new message uses the user's original avatar.
2. Have someone with a custom username set use a command such as /share with the Wordle app. The smaller username in the part of the app's message "<user> used [share]" will use the user's original username.

Expected behavior

1. The custom avatar you set should be used in the reply section of the message.
2. The custom username you set should be used in the reply section of the message.

Discord Build (stable, ptb or canary):
