docs: fix typos in comments, XML docs and messages

[Avicennasis]

Summary

Fix 15 typos across 9 files, each verified against current main. Almost all are XML doc comments / inline comments; two touch message strings (called out below).

Comments and XML docs

• DependencyCall.cs: <param name="request">Data send to dependency</param> -> Data sent to dependency
• DependencyCall.cs: The policy is build and cached at first usage -> is built and cached (1x) and The policy is build at first usage -> is built at first usage (2x)
• DependencyCall.cs: Default timeout strategy used by Polly.TimeouPolicy -> Polly.TimeoutPolicy
• ObjectValidator.cs: ensure that object that not supports NRT is still valid -> that does not support NRT
• ObjectValidator.cs: Validates if instance of object is is not braking NRT rules for objects that not enables it. -> is not breaking NRT rules for objects that do not enable it. (doubled is, braking -> breaking)
• ErrorHandlingMiddleware.cs: we might not be able o wrote to response, so whe just log this fact -> not be able to write to response, so we just log this fact
• ErrorHandlingMiddlewareExtensions.cs: validation handling support of requets -> requests
• ErrorHandlingMiddlewareExtensions.cs: Custom validation confgiruation -> Custom validation configuration
• ErrorHandlingMiddlewareExtensions.cs: <param name="services">Service collections</param> -> Service collection (2x; the parameter is a single IServiceCollection)
• EnumHelper.cs: Tires to parse enum value -> Tries to parse enum value

Strings - please review carefully

• Money.Operators.cs: $"Invalid currency! {c1} is different than {{c2}}" -> {c2}. The doubled braces escape the interpolation, so this exception currently prints the literal text {c2} instead of the second currency. The identical message 30 lines below (in Compare) already uses {c2}.
• QueryDispatcher.cs: $"Multiple handler for query ..." -> Multiple handlers for query ... (exception message)
• ExcludeFromSamplingTelemetryInitializer.cs: log template This rule will be not applied -> This rule will not be applied (word order only; the {FilterKey} / {FilterValue} / {FilterType} placeholders are untouched)
• ErrorHandlingController.cs (Demo): Data = "Custom resposne data" -> "Custom response data"

I grepped the repo for each of these strings - nothing else references them and no test asserts on them.

No versions or CHANGELOGs were bumped, since nothing here changes package behaviour apart from the Money exception text; happy to add those if you would prefer.

Also spotted but not touched, since it was outside the scope I was working from: src/Allegro.Extensions.AspNetCore/README.md line 128 has the same error resposne typo. Say the word and I will include it.
