fix(html/minifier): Fix HTML minifier TS types (#9615)

**Description:**

 - `preserveComments` is optional but required in the TS type

 - `removeRedundantAttributes` is an enum and passing a boolean leads to errors

See https://github.com/swc-project/swc/blob/main/crates/swc_html_minifier/src/option.rs#L54
