feat: add support for json5

[GoodBoyDigital]

Adds support for the .json5 format. Basically allows for json files to have comments and few other quality of life things. See more here

This just upgrades our existing json parser to use the json5 parser instead. Which means json5 files will be transformed to json files.

You can also add comments to your json files and they will be stripped out.

example of valid json5:

myJson.json5

{
    // so cool support for comments
    hello: "world",
    Im: "not broken"
}

woud become:

myJson.json

{"hello":"world","Im":"not broken"}

tests added 👍
