[shazron]

Example:
https://github.com/adobe/aio-cli-plugin-app?tab=readme-ov-file#aio-app-add has See code: to src/commands/app/add/index.ts

Expected:
The code link should point to the actual file, which has a .js extension

Our eslint config has typescript in it, but I forget why I had to add it for this commit: adobe/eslint-config-aio-lib-config@88c8f96
Removing it from the eslint config, publishing a major, and removing typescript from our plugins (and using the updated eslint config) will fix this issue.
