Upgrade to a newer version of YamlDotNet

[tomsseisums]

The project depends on YamlDotNet 6.1.2, where the latest is 11.2.1.

Line 17 in 11381a7

<PackageReference Include="YamlDotNet" Version="6.1.2" />

We hadn't explicitly added YamlDotNet to our project and relied on the internal dependency provided by KubeClient, we ended up having a threading problem related to deserialization which got resolved by explicitly upgrading to a later version.

I came to realization to upgrade by checking YamlDotNet's code and I found out that the v6 implementation in some places are not async/threading friendly, our case was one of them.

The project works otherwise, so I'd imagine it's a safe upgrade.

Thanks! I’ll give this a try and if the tests still pass I’ll put out a new release sometime today 😅
