In Ruby 3.1 those gems were dropped from the stdlib, so they need to be
explicitly installed. Mail should be doing this for us, but since it
cares about Ruby < 2.6, and those gems can't be installed there, they
can't add them to the gemspec without dropping support to old rubies.
Since we don't care about Ruby < 2.7, we can just require them in all
frameworks that use mail.
We had a discussion on the Core team and we don't want to expose this information
as a JSON endpoint and not by default.
It doesn't make sense to expose this JSON locally and this controller is only
accessible in dev, so the proposed access from a production app seems off.

Generally followed the pattern for https://github.com/rails/rails/pull/32034
* Removes needless CI configs for 2.4
* Targets 2.5 in rubocop
* Updates existing CHANGELOG entries for fewer merge conflicts
* Removes Hash#slice extension as that's inlined on Ruby 2.5.
* Removes the need for send on define_method in MethodCallAssertions.
This reverts commit 62aa850fee2070ec3e2d9e4f925dfd7790d27b5e, reversing

There is no reason to disallow mail 2.5 so we don't need to bump the
version constraint since people are still able to use mail 2.6 and get
all the memory saving that was pointed in the pull request description.
Mails downstream dependency (Mime-types) has been shown to decrease
memory usage significantly in its 3.0 release. This memory decrease
will be a big win for users upgrading to Rails 5.
Lets nudge users to upgrade Mail alongside Rails.
This allows Rails users to install mail 2.6 which relaxes
the mime-types dependency, which is a big win for a lot of people.
Previously, the mail gem restricted mime-types to ~> 1.16
but now it has expanded to [">= 1.16", "< 3"]
And the mime-types maintainer will also be checking that
2.x releases don't break mail.

Organized the gemspec files a bit.
* Made quotes more consistent (single quotes dominated, so I used
that).
* Moved license line down a line, separating it logically, and removed
the extra whitespace before its = operator.
* Minor whitespace fixes.
