Docker instructions broken for sqlite.

[externl]

As far as I can tell there's a slight bug in the Docker instructions, but maybe I just did something else incorrectly.

semaphore-docs/docs/administration-guide/installation/docker.md

Lines 43 to 44 in 9a21e50

	# SEMAPHORE_DB_DIALECT: sqlite
	# SEMAPHORE_DB: "/etc/semaphore/semaphore.sqlite"

This env variable did not work. The sqlite database was still created in /var/lib/semaphore/semaphore.sqlite.

SEMAPHORE_DB_DIALECT: sqlite
SEMAPHORE_DB: "/etc/semaphore/semaphore.sqlite"

What did work however was:

SEMAPHORE_DB_DIALECT: sqlite
SEMAPHORE_DB_PATH: "/etc/semaphore"
