[fips140][configurablehttpprovider.TestFunctionalityDownloadFileHTTPS] Skip test if GODEBUG=fips140=only is set (#14076)

<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
#### Description

When
#13926 is
merged, all unit tests in this repository will be run with
`GODEBUG=fips140=only` to help surface any FIPS-140 violations in all
the Go modules in this repository.

One such unit test that fails in these circumstances is
`confmap/provider/internal/configurablehttpprovider.TestFunctionalityDownloadFileHTTPS`.
However, the FIPS violation surfaced by this test is from the test code
itself (as opposed to from OpenTelemetry Collector core code that the
test is exercising), specifically when this call is made:
https://github.com/open-telemetry/opentelemetry-collector/blob/0f3b0c974e235da85282c6d6ff5734e55e8f4fbc/confmap/provider/internal/configurablehttpprovider/provider_test.go#L81

As such, this is not a FIPS violation we need to worry about when
running the OpenTelemetry Collector. To prevent the unit test from
failing when it's run with `GODEBUG=fips140=only`, we skip it.

<!-- Issue number if applicable -->
#### Link to tracking issue
Fixes #13998

<!--Describe what testing was performed and which tests were added.-->
#### Testing

Run the `configurablehttpprovider.TestFunctionalityDownloadFileHTTPS`
unit test with `GODEBUG=fips140=only`.
   ```
   $ cd confmap/
$ GODEBUG=fips140=only go test
./provider/internal/configurablehttpprovider/... -test.v -test.run
TestFunctionalityDownloadFileHTTPS -count 1
   ```
