Error in LaTeX Output for Intervals

[pedromxavier]

When printing intervals with print option MIME"text/latex", both enclosing brackets render as LaTeX errors.

This is probably due to printing "\[" and "\]" instead of plain "[" ... "]" or "\left[" ... "\right]". Any ideia on which is better?

Here's where we do the printing:

MathOptInterface.jl/src/Utilities/print.jl

Lines 298 to 306 in 3f9b256

	function _to_string(options::_PrintOptions{MIME"text/latex"}, set::MOI.Interval)
	return string(
	"\\in \\[",
	_shorten(options, set.lower),
	", ",
	_shorten(options, set.upper),
	"\\]",
	)
	end

We probably just need to remove the \\ and update any tests etc.
