Add constantine to important_packages.nim (#23801)

This adds Constantine to the important packages. Release announcements:
- https://forum.nim-lang.org/t/11935
- https://github.com/mratsim/constantine/releases/tag/v0.1.0

Unfortunately at the moment I'm in a conundrum.

- Constantine cannot compile on devel due to
https://github.com/nim-lang/Nim/issues/23547
- The workaround is changing 
  ```Nim
func mulCheckSparse*(a: var QuadraticExt, b: static QuadraticExt)
{.inline.} =
  ```
  to
  ```Nim
  template mulCheckSparse*(a: var QuadraticExt, b: QuadraticExt) =
  ```
but this does not compile on v2.0.8 due to `gensym` issues despite
https://github.com/nim-lang/Nim/pull/23716

i.e. as mentioned in the issue
https://github.com/nim-lang/Nim/issues/23711 there is another gensym bug
within templates that was fixed in devel but not the v2.0.x series and
that is not fixed by #23716
