Upgrading to ts 4.2 causes issues with function overloads

[johnjesse]

I've made a minimal repro here

with ts: 4.1 - https://github.com/johnjesse/ts-dep-issue/tree/ts-4.1
and ts: 4.2 - https://github.com/johnjesse/ts-dep-issue/tree/ts-4.2

it's actually wrong in both cases - it doesn't cope with overloads well and incorrectly doesn't mark any of the overloads as deprecated with ts 4.1 - and all of them as deprecated with ts 4.2

I've opened this issue to track it - and for visibility - I'll take a look at fixing the rule and test it against my case

Actually - I don't think this is a bug here - I don't think we can know which jsdoc comment to use if an overload doesn't have one - it looks like this was a ts change to how these are resolved - that has been fixed here microsoft/TypeScript#43165

Once I'm sure that's the issue I'll close this Yep - this is the reason
