fix(mock-doc): add inert to HTMLAttributes

[rwaskiewicz]

What is the current behavior?

The inert attribute fails to type check:

fixes: #5071

What is the new behavior?

add inert to the HTMLAttributes interface. this change only allows the attribute to properly type check in TSX. it does not polyfill the functionality for browsers that do not support inert.

Does this introduce a breaking change?

• Yes
• No

Testing

Check out and build this branch:

npm ci \
&& npm run clean \
&& npm run build \
&& npm pack

Install it in the output of creating a new stencil component library:

cd /tmp \
&& npm init stencil@latest component inert-test \
&& cd $_ \
&& npm i [PATH_TO_STENCIL]

Open src/components/my-component/my-component.tsx in your editor, and inert to a JSX element. It should not properly type check:

That's the same number of errors on main, so at least we're not creating new ones!
