Remove deprecated forge webtrigger root command

What's changing

We are removing support for the forge webtrigger root command to create URLs, as the deprecation window has passed. This change follows the initial deprecation announcement earlier last year.

The forge webtrigger command now requires a specific sub-command. Using the root command to generate a web trigger URL will no longer work.

What you need to do

To create a web trigger URL via the CLI, you must now use the officially supported create sub-command:

• Run the following command in your app's top-level directory:

forge webtrigger create

• Follow the prompts to select your installation context and the web trigger function.
• Alternatively, you can specify the function key directly:

forge webtrigger create --functionKey <your-function-key>

For more information, see the forge webtrigger create CLI reference.
