Clarify activity pause timeout behavior

[JLDLaughlin]

What changed?

Clarifies temporal activity pause --help to state that pausing an Activity does not stop or extend the Activity's Schedule-To-Close Timeout.

Regenerated internal/temporalcli/commands.gen.go from internal/temporalcli/commands.yaml.

Why?

The existing help explains that Pause prevents future retries and does not interrupt some in-flight attempts, but it does not mention that Schedule-To-Close continues running while paused.

That can surprise operators because "pause" can imply the Activity is safe from timing out. This adds the timeout caveat and points users to temporal activity update-options before a long pause.

Testing

go run ./cmd/gen-commands \
  -input internal/temporalcli/commands.yaml \
  -pkg temporalcli \
  -context "*CommandContext" \
  > internal/temporalcli/commands.gen.go

go run ./cmd/temporal activity pause --help

go test ./cmd/gen-commands

Verified the help output includes the Schedule-To-Close warning.
