test: Ensure there's a single non-deprecated attribute per alias group

[lcian]

• Adds a test to ensure that, for each group of attributes that alias each other, there should be (at most) a single canonical way to name that attribute, all of its aliases should be marked as deprecated.

• Address test failures by editing the conventions in the following ways:

Group [ai.input_messages, gen_ai.prompt, gen_ai.request.messages]
has 2 non-deprecated attributes: [gen_ai.prompt, gen_ai.request.messages]

Action: deprecated gen_ai.prompt in favor of gen_ai.request.messages.
Reason: gen_ai.prompt is deprecated in OTEL.

Group [http.route, url.template]
has 2 non-deprecated attributes: [http.route, url.template]

Group [params.<key>, url.path.parameter.<key>]
has 2 non-deprecated attributes: [params.<key>, url.path.parameter.<key>]

Group [sentry.release, service.version]
has 2 non-deprecated attributes: [sentry.release, service.version]

Group [client.address, http.host, server.address]
has 2 non-deprecated attributes: [client.address, server.address]

Group [http.response.body.size, http.response.header.content-length, http.response.header['content-length'], http.response_content_length]
has 2 non-deprecated attributes: [http.response.body.size, http.response.header.content-length]
