[Chore]: Add XML comments for visible types or members

[Dor-bl]

Many Complier Warnings CS1591 are found in the project. Any assistance with those would be great! https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/compiler-messages/cs1591?f1url=%3FappId%3Droslyn%26k%3Dk(CS1591)

some examples:

I would like to possibly help with this; I spotted some that are obvious to amend but the majority are about Missing XML comment for member. Ideally, do you envision everything having an adequate comment or do you plan to disable the warning in certain classes / for certain scenarios/members etc. ?

[Dor-bl]

Hi @dragojs. Thank you for reaching out first of all, any help would do. The idea is to add comments whenever possible, rather than just disable the warnings. You can start with a small PR at first and I assume that with time you will be able to send bigger PR's.

If you're still looking for some help, I'd love to contribute. I'm going to fork the repo and take a look tonight. Let me know how I can best work with you.

[dragojs]

There are some plain obvious fixes which I touched right away and knocked out about 100 warnings but really I just scratched the surface. For most of the others you really have to scratch your head to figure out what a suitable comment is. I'd probably look at how other clients tackled this; can't really think of a better approach

[Dor-bl]

@sambrandt @dragojs I'm not sure where you guys stand with this, but I came across a relatively easy fix for warnings related to cref. you can check out this PR for examples: https://github.com/appium/dotnet-client/pull/752

Went the same route; haven't had as much time as I wished to dedicate to this; there are several few improvements on a branch of mine that refers to this, I can possibly try to PR later this week. Looked a bit in the java client and there's either barely any comments or I'm looking in the wrong place. The python client however does have some comments to serve as inspiration

Hey! Sorry, I started to work, and then life exploded a bit. I'm hoping that this week I can get some traction on this. Thanks for the reference, I'll take a look at it.
