Declarations folder on server leaves a dirt git after install

[martinratinaud]

It's not really a problem and we can keep it like this but while investigating failing deployment of contrib, I found it weird that git status gave a not clean folder and I got a bit confused.

In fact, the deployment process

• creates a pm2.config.cjs file
• creates a .env file
• replace the name of package-lock with the name of the folder

that are then not versioned files in git.

This could be fixed if need be by

• adding a .gitignore (either in declarations repo or through ansible by appending those rules to existing ones)
• changing the name inside package-lock.json of declarations repo with ${instance} instead of ${instance}-declarations
