html: Add missing condition to 'in cell' insertion mode, required by spec

In section 12.2.6.4.15 of the spec, there is a condition that the current node is a td or th element, which is not implemented. This can lead to a panic when the open elements stack is popped whilst empty, as outlined in golang/go#30600. This commit implements that check.

Fixes golang/go#30600
