Proposed commit message

trend_micro_vision_one: reword telemetry CEL comment to avoid policy flake

The daily Serverless policy test for the telemetry data stream
intermittently failed because Fleet on Serverless re-emits the
`program: |` literal block scalar differently from the local 9.4.0
stack. When a comment contained a quoted phrase that spanned two
adjacent lines, the re-emitted YAML folded those lines into one and
the resulting policy no longer matched the expected output.

Drop the cross-line double-quoted phrase in the CEL comment block and
update both policy test expectations so the template and expected
output stay consistent. This is a content-level workaround; the
underlying emitter behaviour in Serverless is not addressed here.

Fixes #18519, #18518

Note

No changelog: this only adjusts a comment in the telemetry CEL program and the corresponding policy-test expectations. Not a user-facing change.
