Fix default value of poll.interval.ms in MongoDB connector docs

[DominiQN]

The default value of poll.interval.ms is incorrectly documented as 1000ms in some parts of the documentation.

According to the source code and description, the correct default value is 500ms.

	public static final Field POLL_INTERVAL_MS = Field.create("poll.interval.ms")

	.withType(Type.LONG)
	.withGroup(Field.createGroupEntry(Field.Group.ADVANCED, 17))
	.withWidth(Width.SHORT)
	.withImportance(Importance.MEDIUM)
	.withDescription("Time to wait for new change events to appear after receiving no events, given in milliseconds. Defaults to 500 ms.")
	.withDefault(DEFAULT_POLL_INTERVAL_MILLIS)
	.withValidation(Field::isPositiveInteger);
