[TASK] Upgrade @types/bootstrap to 5.1.6

This resolves a todo in Tooltip.ts, where we've waited
for an updated types definition for bootstrap. Now
some new methods, like Tooltip.getOrCreateInstance,
are known to TypeScript and can be used, without
setting an ignore comment.

Command used:
> yarn upgrade @types/bootstrap --latest
