Decode values from OTEL_RESOURCE_ATTRIBUTES

[lgfa29]

While using the Go SDK I noticed an inconsistency in how OTEL_RESOURCE_ATTRIBUTES baggage values are encoded and decoded. This was due to a difference in the version of the W3C Baggage spec used for baggage propagation and the OTEL_RESOURCE_ATTRIBUTES decoding.

open-telemetry/opentelemetry-specification#2670 updates the W3C Baggage spec version used by the Resource spec to require percent-decoding values from OTEL_RESOURCE_ATTRIBUTES.
