Underline tag <u> or <ins> didn't interpret

[rilysh]

By default, markdown support underline by <u> or <ins> HTML tags. But for some reason, I can't able to use these tags with glamour. I'm not sure is this feature already implemented or not. Also, there is a kind of lack in documentation, so I can't be sure.

Steps to reproduce

package main

import (
      "fmt"
      "github.com/charmbracelet/glamour"
)

func main() {
    msg := "<u>this supposed to be an underline, isn't it?</u>"
    render, _ := glamour.Render(msg, "dark")
    fmt.Println(render)
}

Expected Behavior

Like URLs, <u> or <ins> tag should represent that this is an underline text.

Actual Behavior

But it didn't

According to Markdown docs, this is the only standard way to do underline in Markdown. https://www.markdownguide.org/hacks/#underline
