fix(experimental-utils): add endLine and endColumn

[SimenB]

The end{Line,Column} are nice to verify ranges of error messages.

typescript-eslint/packages/experimental-utils/src/ts-eslint/Linter.ts

Lines 95 to 96 in 89c87cc

	endColumn?: number;
	endLine?: number;

Couldn't find anywhere where its omission was discussed

Thanks so much for publishing these! Will be converting eslint-plugin-jest to use them.

I never bothered with them as 99% of the time when we report an error, we pass in the node.
Which means that you're not overly concerned with the end line, just a line+col(+node name) combo.

Happy for them to be added though!
