Add semconv/v1.7.0 package

[MrAlias]

Generated from the v1.7.0 release of the specification using the semconvgen tool manually. This also updates the project to use this version of the semconv package.

This does not include the prior, and missing, v1.5.0 and v1.6.0 versions of the semconv package. They are planned to be added in a follow-on PR.
