vim-patch:05e44e9: runtime(tex): add amsmath support to tex syntax script (#35958)

Browse Source 
Problem:  tex syntax file does not support some of the math equation
          environments provided by amsmath.sty, therefore well-formed
          snippet is highlighted as "texBadMath"
Solution: add the environments

closes: vim/vim#18433
