update instrumentations to semconv 1.32 (#369)

SemConv 1.32 deprecates a couple of attributes which we use extensively:
- code.function.name is now an FQN (including class name)
- code.namespace is deprecated (included in code.function.name)
- code.linenumber is deprecated and replaced with code.line.number

Updated all packages to conform, updated min semconv to 1.32, and made
a couple of minor changes"
