IEEEeqnarray not recognized as math environment when using `ieeecolor` class

[ThomasChaffey]

Description

Essentially the same issue as one I raised previously: #2675 (comment)

IEEEeqnarray is not automatically recongized as a math environment when using the ieeecolor class. A workaround is adding

let g:vimtex_syntax_packages = {
      \ 'ieeetrantools': {'load': 2},
      \}

to .vimrc.

ieeecolor replaces the older IEEEtran as the submission template for some IEEE journals.

If I understood correctly, then this is fixed now. :)
