Add "sealing order" to CL contact form

[s-taube]

On the CourtListener contact form, when a user selects the Issue Type "Case Removal Request," they should be required to make an additional selection:

    Do you have a court-issued sealing order?
    - Yes (will we ask you for a copy)
    - No

In addition, updates need to be made to the email that is sent from the form:

• If the user selects "Yes," the email should include "Issue Type: Sealing Order"
• and if the user selects "No," the email can include "Issue Type: Case Removal Request"

No strong preference on UI, but an example is to add a single-select dropdown that is grayed-out, and only active when "Case Removal Request" is selected.

• "No" would be the default option.
• We would also want to change the default "Issue Type" to "Support." The default is currently "Case Removal Request," and asking for a sealing order by default could be confusing to many users.

@mlissner look about right?

I think that'd work, but I think there's an easier way. In my inbox, I have a rule that looks for any of these words to categorize a sealing request:

• "time-senstive"
• urgent
• seal
• stricken
• redacted
• psuedonym
• "press coverage"
• anonymity

That's a bit overinclusive, but it works easily enough.

Could we just do that and keep the contact form simple, @s-taube?
