chore!: bump target versions to iOS13 and others (#451)

Bumps supported versions of platforms:
- iOS "12.0" -> "13.0"
- watchOS "4.0" -> "6.0"
- tvOS "12.0" -> "13.0"
- masOS "10.13" -> "10.15"

**Requirements**

- [x] I have added test coverage for new or changed functionality
- [x] I have followed the repository's [pull request submission
guidelines](../blob/v9/CONTRIBUTING.md#submitting-pull-requests)
except I launch unit tests using "swift test" due not having Apple
Developer Account
- [x] I have validated my changes against all supported platform
versions

**Related issues**

OpenTelemetry specifies iOS13 in their package file

https://github.com/open-telemetry/opentelemetry-swift/blob/main/Package.swift

**Describe the solution you've provided**

Alternative would be using feature branch or forking and refactoring
OpenTelemetry to iOS12

**Additional context**

Observability teams uses OpenTelemetry has lowest target iOS13. We need
to bump platform versions in LD SDK. To be able build Observability
library.
As far we know we don't have customers on iOS12
