fix(utils): make SVGO not remove title (#6684)

* chore(utils): add `removeTitle: false` to svg loader

By default, SVGR removes the `<title>` tag from SVG inputs.
This hinders a11y since "the `<title>` element provides an
accessible, short-text description of any SVG container
element or graphics element".

Modern browsers also show tooltips on hover for inline
SVG with the `<title>` tag.
