Ignore node_modules

[mibradev]

This will add /node_modules to .gitignore and also add a new line before /app/assets/builds/*.

Before:

...
# Ignore master key for decrypting credentials and more.
/config/master.key
/app/assets/builds/*
!/app/assets/builds/.keep

After:

...
# Ignore master key for decrypting credentials and more.
/config/master.key

/app/assets/builds/*
!/app/assets/builds/.keep

/node_modules

I separated the commands to make sure we don't append /node_modules twice.

Can do it in the same append 👍

I mean If we already have for example:

/node_modules
/yarn-error.log
yarn-debug.log*
.yarn-integrity

the result will be:

/node_modules
/yarn-error.log
yarn-debug.log*
.yarn-integrity

/app/assets/builds/*
!/app/assets/builds/.keep

/node_modules

with duplicated /node_modules. That's why I called append_to_file twice, the second one search only for \n/node_modules\n. If I combined them it will search for the whole expression \n/app/assets/builds/*\n!/app/assets/builds/.keep\n\n/node_modules\n.
