Enforce jsdoc/check-indentation

[edg2s]

This rule was pulled out of #211 because it caused too many false positives:

• It doesn't like "indents" for continued text describing parameters/etc. which makes a serious mess of some of our VE stuff.

This can be fixed by adding param/return to the excludeTags option (in addition to example). This would still leave descriptions containing bullet lists (1 in VE, probably more in core), so we could just disable the rule, it doesn't catch a huge amount.

If we managed to fix the rule to allow indentation of all multi-line text blocks, the only errors we would catch would be ·*··@tag -> ·*·@tag.

Update: Should probably be disabled without gajus/eslint-plugin-jsdoc#541. Lots of false positives in mw-core.

That can be revisited if gajus/eslint-plugin-jsdoc#541 gets resolved.
