fix: quote() should include newline in literal

[dsherret]

The output wasn't including new lines. The following:

export const loaderText = "export async function cacheToLocalDir(url, decompress) {\
    const localPath = await getUrlLocalPath(url);\
    if (localPath == null) {\
        return undefined;\
    }\

Should actually be:

export const loaderText = "export async function cacheToLocalDir(url, decompress) {\n\
    const localPath = await getUrlLocalPath(url);\n\
    if (localPath == null) {\n\
        return undefined;\n\
    }\n\
