Add suggestion for opening monika config generator page when running Monika the first time

[ilmiawan]

Describe the bug Currently when we try to run Monika in the first time, there is an error state that there is missing configuration file and link to monika example.

To Reproduce Steps to reproduce the behavior:

1. Go to empty directory
2. run npx run @hyperjumptech/monika
3. See error

Expected behavior When first time Running and cannot find configuration, directly open monika config generator in local browser.

Not only first time though. But every time configuration file not found.

This is how Fossil did it. https://fossil-scm.org/home/help?cmd=ui

This is how git did it. (although its read only)

git instaweb -httpd=webrick

fish_config is a fantastic prior-art: https://fishshell.com/docs/current/cmds/fish_config.html

For first iteration, let's do this:

• [ ] When monika cannot find a configuration file, show the following message:

Configuration file not found. By default, Monika looks for monika.json configuration file in the current directory. Otherwise, you can also specify a configuration file using -c flag as follows

monika -c <path_to_configuration_file>

You can create a configuration file via web interface by opening this web app: https://hyperjumptech.github.io/monika-config-generator/

• [ ] When monika is run with --create-config flag, open the browser and navigate to https://hyperjumptech.github.io/monika-config-generator
