Bump DatadogTestCollector and DatadogTestLogger to 0.0.55 (#8949)

## Summary of changes

Bumps the `DatadogTestCollector` and `DatadogTestLogger` package
references from `0.0.54` to `0.0.55` in the tracer and profiler test
projects.

## Reason for change

Consume version `0.0.55` of the Datadog test tooling.

## Implementation details

- Update the shared tracer test package references.
- Update the profiler integration test logger reference.

## Test coverage

- `git diff --check` passes.
- `dotnet restore
tracer/test/Datadog.Trace.TestHelpers/Datadog.Trace.TestHelpers.csproj
--disable-parallel --force-evaluate` currently fails with `NU1102`
because `DatadogTestLogger 0.0.55` was not yet available from the
configured NuGet or Azure feeds at validation time.
`DatadogTestCollector 0.0.55` is available.
- No test suite was run because restore could not complete.
