[Bug] The `.gitignore` file does not include `.DS_Store`

[possumbilities]

Description

The .gitignore file does not include .DS_Store, it should be included it to prevent accidental commits including it.

Expectation

.DS_Store should not be picked up in this repository by git.

See Vocabulary's .gitignore as an example:

• https://github.com/creativecommons/vocabulary/blob/main/.gitignore

Resolution

• [x] I would be interested in resolving this bug.
