criteria clarification: change HTTP to HTTP(S) and drop FTP in select criteria

[Kamil Paral]

This has been already discussed before [1], but the discussion died down.
Here's an updated proposal.

Change the following:

1.
https://fedoraproject.org/wiki/Basic_Release_Criteria#Remote_package_sources
From: "When using a release-blocking dedicated installer image, the
installer must be able to use either HTTP or FTP repositories (or both) as
package sources. Release-blocking network install images must default to a
valid publicly-accessible package source."
To: "...must be able to use HTTP(S) repositories as package sources..."
Also add a new footnote:
"Covered repository types
This criterion only covers direct repository URLs ("baseurl"), and doesn't
cover mirrorlist or metalink URLs."

2. https://fedoraproject.org/wiki/Basic_Release_Criteria#Update_image
From: "The installer must be able to download and use an installer update
image from an HTTP server."
To: "...from an HTTP(S) server."

3.
https://fedoraproject.org/wiki/Fedora_33_Beta_Release_Criteria#Remote_pac...
From: "When using the dedicated installer images, the installer must be
able to use HTTP, FTP and NFS repositories as package sources."
To: "...must be able to use HTTP(S) and NFS repositories..."
Also update its footnotes in the same spirit.
Also add a new footnote:
"Covered repository types
This criterion only covers direct repository URLs ("baseurl"), and doesn't
cover mirrorlist or metalink URLs."

It will also have an effect on our test cases:

4.
https://fedoraproject.org/wiki/QA:Testcase_install_repository_HTTP/FTP_gr...
Rename to QA:Testcase_install_repository_HTTP_graphical
Update the contents by replacing HTTP with HTTP(S) and dropping FTP
mentions.

5.
https://fedoraproject.org/wiki/QA:Testcase_install_repository_HTTP/FTP_va...
Rename to QA:Testcase_install_repository_HTTP_variation
Update the contents by replacing HTTP with HTTP(S) and dropping FTP
mentions.

6. https://fedoraproject.org/wiki/QA:Testcase_Anaconda_updates.img_via_URL
Update the contents by replacing HTTP with HTTP(S).
