Weird message in the `Agency` tab of new invitation

[JanCizmar]

Describe the bug There is a message:

You can invite the agency after creating a professional translation request. 
Go to Project tasks and click! Translation to send a request to the agency for cost estimation.

Which is not truth. The invitation is created automatically when user is invited, so why do we have it in the invitation dialog?

To Reproduce Steps to reproduce the behavior:

1. Go to 'Member'
2. Click on 'Invite user'
3. Go to agency tab

Expected behavior The agency tab is not present in the invitation dialog.

The note may not be clear enough. But there is one way: when you don't invite an agency to the project during "ordering translation" process, so then you need a way to do it (an agency invitation will differentiate a whole group of users from the agency).

Dialog There is checkbox, in the translation ordering (basicaly agency is not always allowed to see the data in Tolgee.

Default value

Let's simplify the copy with the link to Ordering professional translation in docs.

What do you think @stepan662? Of course, it should be according to our design rules.

I think the issue is that the tab is there even when no request to agency has been sent. So @JanCizmar is saying: instead of disabling the form, hide the whole tab. Do I understand it correctly? @JanCizmar

I din't know about this case. Then I think it's ok. I would maybe wrap the mesage with info alert, because the typography looks odd, but other then that I think we can leave it as it is.
