Docs: improved seeEmailIsSent description

[ThomasLandauer]

Added info about Console, see Codeception/Codeception#4698

Hey @ThomasLandauer , you're right 😃, currently the way emails are verified is through the Profiler, and that requires a web request. So that's right, currently Codeception can't detect emails sent via CLI... But it could :). I can think of several ways to implement this:

• Message Events.
• Checking email spool
• Persisting sent mails to a file. Or...
• Through the 'logger' service as they do here for SwiftMailer or here in Symfony Mailer itself.

So this is another 'not yet implemented' issue, and i think it could be even better if an issue is opened requesting that feature. and instead of just saying "codeception can't do it", you could add a link to the issue in the description, so that people can see if someone has contributed that feature (and has been merged) or not.

[ThomasLandauer]

Yeah, great! Judging from @DavertMik's answer (see above) I thought it's not possible in principle.

Would you create that issue? I can't say much - I would just copy your text from above... ;-)

[TavoNiievez]

I personally would prefer to present the corresponding PR directly,
achieving this may involve editing various methods in the module, so i could try to implement it after the PRs i currently have open are merged or not (owners can ask me for changes there too).

[ThomasLandauer]

Yeah, sure! I changed "Codeception cannot detect it." to "Codeception cannot detect it yet." - to give a hint that there's some progress underway.

So I'd say this docs PR here can be merged for now.
