Describe the bug
Environment Variable MEILI_IGNORE_DUMP_IF_DB_EXISTS requires a value but documentation says it requires a value to not be present.

To Reproduce
Steps to reproduce the behavior:

1. In docker compose, set - MEILI_IGNORE_DUMP_IF_DB_EXISTS= (empty string)
2. Start meilisearch.

Expected behavior
Dump should be ignored without error if db already exists.

Meilisearch version:
v1.3

Hey, yes, I see your problem. We must update the documentation.

If you’re using the CLI flag, as the documentation states, you should use the flag and don’t specify any value: ./meilisearch --ignore-dump-if-db-exists --import-dump xxxx.dump.
If you’re using the environment variable or the config file, you must assign the value true or false as stated in the error message: MEILI_IGNORE_DUMP_IF_DB_EXISTS=true MEILI_IMPORT_DUMP=xxxx.dump ./meilisearch.

This has been true for all versions since the v1.0 of Meilisearch I believe.
