What happened?

When using .getHTML(false), I got the error message error TS2559: Type 'false' has no properties in common with type 'GetHTMLOptions'.

What is your expected behavior?

According to https://github.com/webdriverio/webdriverio/blob/main/packages/webdriverio/src/commands/element/getHTML.ts#L79-L80, getHTML was meant to retain backwards-compatibility. However, the type definition options: GetHTMLOptions doesn't allow that. The definition should likely instead be options: GetHTMLOptions | boolean.

How to reproduce the bug.

await browser.$("#example").getHTML(false);

Relevant log output

error TS2559: Type 'false' has no properties in common with type 'GetHTMLOptions'
