Deno employs a dedicated configuration file named deno.json. This pull request introduces the capability to load commitlint configuration directly from deno.json, enabling developers using Deno to eliminate the need for a package.json file.

Description

I am opening this pull request as a draft to share the changes I've made, as some parts of the codebase are still unclear to me. I welcome feedback from more experienced contributors who can use this as a foundation. Additionally, my commit includes formatting changes made by formatter automatically executed when committing.

I have added check whether deno.json exists to isEsmModule function as deno.json (JSR) packages support ESM only.

Motivation and Context

Deno supports loading configuration from package.json, which allows commitlint to function seamlessly. However, if developers prefer to use only deno.json for their configuration without relying on a separate config file, this is currently not feasible, as commitlint exclusively loads its configuration from package.json.

How Has This Been Tested?

Currently, I am unable to pass the tests due to the modifications I've implemented.
