Add v5.3.0-beta1 package updates

[onesignal-deploy]

Changes

• upgrade RestSharp from v106 to v108

[Aleksander98]

Please remember to lock NuGet package dependencies to a specific major version. This can be done by specifying the version range in the PackageReference e.g. <PackageReference Include="RestSharp" Version="[108.0.3,109.0.0)" />

[108.0.3,109.0.0) means: allow any version greater than or equal to 108.0.3 but less than 109.0.0.

Please update other packages as well (e.g., Polly) and lock their versions using the same approach.

For more details and best practices, please refer to the official documentation:

Thanks for the feedback @Aleksander98. I have a PR in upstream to do this, just need to get it merged there and then we can release this.
