Adding github action for automated submission

[louisgv]

Hi @ninoseki!

Thanks for making mitaka - I love it! It's much more powerful than a lot of OSINT tool I have used in the past! I thought about contributing and found that your project doesn't have automated store submission yet. Thus, I created a github action incorporating bpp that can submit the zip to the Chrome/Firefox stores automatically for you. It is set to run manually from the github action tab, but we can tweak it to run as frequent as you wish! The only thing you would need to create is a SUBMIT_KEYS github repository secret.

This secret is a json, with the schema defined here.

Here's a sample keys for your project:

{
  "$schema": "https://raw.githubusercontent.com/plasmo-corp/bpp/v1/keys.schema.json",
  "chrome": {
    "clientId": "123",
    "refreshToken": "789",
    "extId": "abcd"
  },
  "firefox": {
    "extId": "123",
    "apiKey": "abcd",
    "apiSecret": "abcd"
  }
}

You can find instructions on how to get those keys in the schema, or if you use vscode, the schema should provide hint/intelisense when hovering over the json properties. If you need any help in setting up the keys, feel free to @ me! Otherwise if this doesn't seem necessary, feel free to close the PR :)
