Brave prompts to create new keychain named "Default Keychain"

• Describe the issue you encountered:

With the recent muon change to encrypt cookie data at rest, Brave now has a hard dependency on gnome-keyring on linux (before it was only needed if you opted to use the builtin password manager). As a result, if you do not already have a keychain, Brave will prompt you to create a new one. I cannot confirm, but I would imagine that if there is an existing keychain, the user would be prompted to allow access. If possible we should use a keychain name that better indicates why Brave is asking for keychain access.

Furthermore, despite being used to protect user data - having to allow keychain access will be seen by some users as concerning. Some users will want a way to stop all requests for keychain access.
