[fix][broker] Added newline to end of standalone.conf

[marksilcox]

Motivation

Without a new line at the end of the file, running apply-config-from-env-with-prefix.py with a new property appends directly to the file so you end up with something like managedLedgerMaxUnackedRangesToPersistInZooKeeper=-1myotherproperty=value and startup fails

Modifications

Added a new line at end of file

👍

In any case, the script was also already fixed to handle it:

pulsar/docker/pulsar/scripts/apply-config-from-env.py

Lines 78 to 80 in 17db729

	# Ensure we have a new-line at the end of the file, to avoid issue
	# when appending more lines to the config
	lines.append('\n')

that is missing from apply-config-from-env-with-prefix.py

Oh, gotcha. Do you mind creating a PR to fix it there too? :)
