Rename `ConstantsInsteadOfLiterals` detector to better suit `//aderyn-ignore-(..)`

[TilakMaddy]

Before:

// aderyn-ingore-next-line(constants-instead-of-literals)
uint256 y = 1034 + x * g;

Problem: It doesn't make sense to ignore the fact that constants are being used instead of literals

Other examples: we say aderyn-ignore-next-line(empty-block) .. we don't say aderyn-ignore-next-line(filled-block)

We state the problem in the detector's name

So I have renamed this

// aderyn-ingore-next-line(literal-instead-of-constant)
uint256 y = 1034 + x * g;

Now it reads, "ignore the fact that it's a literal instead of a constant"
