Incorrect statement about Views in OpenTelemetry Overview

[alfiejfs]

The overview page has a section on views, where it is incorrectly stated that views can be applied through a Meter. I believe the wording is correct on the metrics SDK page view section where only MeterProvider is mentioned.

It is correct they are applied at the meter level. The instrument selection criteria allows for a view to be applied to an entire meter (name/version).

They are configured at the meter provider level.

The specification, as it is currently written is correct. I imagine the confusion comes from the last point about the view being configured at the meter provider level though. Updating the specification to clarify that point seems reasonable.

@MrAlias good spot! I agree - I think the wording is just slightly unclear. I will amend my PR.

Upon re-reading, I don't think it is necessary to specify that they can be applied globally or to specific meters at all then. This seems to specific to include in the overview. I think I might be a fan of just specifying that they can be configured through the MeterProvider.
