fix: 🐛 font format could be without qoutation

[dews]

Description

Use document.styleSheets[index].cssRules[0].cssText to get font-face, (index is dependent on styleSheets load order)
On windows,

@font-face { font-family: "Material Design Icons"; src: url("https://cdn.jsdelivr.net/npm/@mdi/font@6.5.95/fonts/materialdesignicons-webfont.woff2?v=6.5.95") format("woff2"), url("https://cdn.jsdelivr.net/npm/@mdi/font@6.5.95/fonts/materialdesignicons-webfont.ttf?v=6.5.95") format("truetype"); font-weight: normal; font-style: normal; }

But when using Safari on iOS or Safari/Chrome on iPhone,

@font-face { font-family: "Material Design Icons"; src: url(https://cdn.jsdelivr.net/npm/@mdi/font@6.5.95/fonts/materialdesignicons-webfont.woff2?v=6.5.95) format(woff2), url(https://cdn.jsdelivr.net/npm/@mdi/font@6.5.95/fonts/materialdesignicons-webfont.ttf?v=6.5.95) format(truetype); font-weight: normal; font-style: normal; }

From W3C, https://drafts.csswg.org/css-fonts/#font-face-src-parsing, example22 you can see the format is unquoted.
