[Fix] Metafile.yml: Fix typo of all config file path.

[kbumsik]

Motivation

While I look thorough the model zoo using mim, I found that there are some models failed to download because of the wrong config file path in metafile.yml (all weights links are OK btw.)

Related: open-mmlab/mim#192

Modification

Fix all possible typos in metafile.yml. Now mim should be able to download all model configs without error!
