    feat(source): teams: bitbucket: enforce that username must be atlassian email address (#6585)
    
    I tried configuring a bitbucket codehost with an API token. I typed in `sourcegraph-testing` as the username, and the API token has the password. However, that didn't work and I saw this page:

    https://support.atlassian.com/bitbucket-cloud/docs/using-api-tokens/#Using-API-tokens-with-Bitbucket-APIs
    
    This docs page mentions that when using the API token, you need to specify your **atlassian account email** as the username. So, I adjusted the resolver to check to see if the provided username is a valid email address. I also adjusted the text on the connection page to say that you need your email address (and adjusted the input type to reflect this).
    
    
    ## Test plan
    
    The new account page looks like this:

    After plugging in the credentials, I see the workspaces populate the sidebar:

    I went back and also tried plugging an invalid email address into the connection page. Now, you can see that the input box warns the user that something is wrong with the input. Also, when I click the button the backend correctly returns an invalid parameter error
