Incorrect event name 'changed'

In line 782 of README.md

playground-elements/README.md

Line 782 in 50f5800

| `changed` | User made an edit to the active file |

The event name is written as changed which is incorrect, as the Event in the source code uses the name change

playground-elements/src/playground-code-editor.ts

Line 493 in 50f5800

this.dispatchEvent(new Event('change'));

btw on line 811 of README.md

playground-elements/README.md

Line 811 in 50f5800

## `<playground-file-system-controls`

a closing bracket is missing

I normally would create a pull request and correct this, but I need my employer's approval for signing the CLA. I was advised to create an issue instead. I know this is not an ideal situation. I would be very grateful if the maintainer or someone else could pick this up.

Thanks

Thanks for the issue! Great catch. I can look into this!

Thank you! Fixed in #297

Thank you!
