Prompt the user with a clearer warning that their email alias will be removed if they accept an email invitation directed to it.

In Bitbucket Cloud, users cannot accept email invitations intended for their mail alias because it will result in Bitbucket Cloud prompting the user to create a new account for it.

Accepting it will result in a new account creation and removing the email alias from the original account to be associated with the new account.

This behavior has already been raised in BCLOUD-14335.

To avoid the above behavior from happening accidentally or by mistake by the user, the UI should provide the user with a clearer warning that if the email is an email alias, it will proceed to remove it and associate it with the new account.
