chore: VCAP_SERVICES_FILE_PATH compatibility using greedy matchers

[PDT42]

Improve VCAP_SERVICES Service Binding Resolution with Greedy Matchers

Chore

🔧 Updated service instance matching for SAP Cloud Logging and Dynatrace to use greedy (array-based) VCAP matchers, extending the default matching without breaking existing behavior. Error messages and documentation have been updated to guide users toward the correct configuration.

Changes

• package.json: Updated vcap matching for telemetry-to-dynatrace and telemetry-to-cloud-logging from a single object to an array of matchers. Dynatrace now matches by label: "dynatrace" or tag: "dynatrace"; Cloud Logging matches by label: "cloud-logging" or tag: "Cloud Logging".

• lib/utils.js: Improved inline comments to clearly document the legacy compatibility behavior for getCredsForDTAsUPS() and getCredsForCLSAsUPS(). Updated the warning message for Cloud Logging user-provided services to recommend only the "Cloud Logging" tag (dropped "cloud-logging" from the recommendation).

• lib/logging/index.js, lib/metrics/index.js, lib/tracing/index.js: Improved error messages when credentials are not found — now explicitly instruct users to ensure the bound service instance uses the correct tag ("Cloud Logging" or "dynatrace").

• README.md: Clarified that user-provided service instances for SAP Cloud Logging must use the tag "Cloud Logging" (removed reference to the legacy cloud-logging tag). Added a tip with the cf update-user-provided-service command and a link to CAP's service binding documentation.

The PR makes good improvements — error messages are more actionable, matching predicates are extended via vcap arrays, and comments are clearer. The one substantive issue is that the silent match on the deprecated "cloud-logging" tag in getCredsForCLSAsUPS() is inconsistent with the PR's stated intent to promote "Cloud Logging" as the sole required tag; it should emit the same deprecation warning as the name-based fallback.
