feat(attributes): Add network connection-related attributes

[Lms24]

Description

This PR adds attributes sent from the JS SDK describing network connections. As we discussed in Slack, we want to take the opportunity to move the non-existing/suboptimal attribute names over to properly name-spaced attribute names.

Old attribute (deprecated)	New attribute	New attribute In OTel
connectionType	network.connection.type	Yes
effectiveConnectionType	network.connection.effective_type	No
connection.rtt	network.connection.rtt	No

I checked an none of these attributes are used in dashboard prebuilt configs.

Worth noting: In contrast to the strict OTel definition of network.connection.* attributes, the values sent from the browser SDKs are estimations and not actual values. I think this is generally fine as other SDKs can still send these attributes with the actual numbers. We also discussed this in slack and no-one had strong opinions. I'd err towards running with these attributes to avoid creating yet more custom attributes.

PR Checklist

• I have run yarn test and verified that the tests pass.
• I have run yarn generate && yarn format to generate and format code and docs.

If an attribute was added:

• The attribute is in a namespace (e.g. nextjs.function_id, not function_id)
• I have used the correct value for pii (i.e. maybe or true. Use false only for values that should never be scrubbed such as IDs)

If an attribute was deprecated:

• I've followed the policies described in CONTRIBUTING.md
