apacheGH-49493: [C++][Python] Add OpenTelemetry to our CMakePresets when bulding python-maximal (apache#49494)

### Rationale for this change

OpenTelemetry can be enabled when building Python. It is currently missing from the `CMakePresets.json`

### What changes are included in this PR?

Add a `features-opentelemetry` which is added as part of `features-python-maximal`. This one is used for `ninja-debug-maximal` or other maximal features.

### Are these changes tested?

I tested locally with `ninja-debug-maximal` and validated that OpenTelemetry was enabled. I don't think we test our presets on CI (at least I haven't been able to find any `--preset ` presence)

### Are there any user-facing changes?

If a user is building using presets, now OpenTelemetry will be built, as expected.
