WithProfile not respected in custom rendered

[goyapara-deshaw]

Describe the bug
When a custom renderer is defined with the WithProfile method, it is not being respected, when TERM=xterm and COLORTERM is unset.

Setup
Please complete the following information along with version numbers, if applicable.

• OS Linux
• Shell bash
• Terminal Emulator PuTTy

To Reproduce
export TERM=xterm
unset COLORTERM

and run the below code:

package main

import (
        "fmt"
        "os"

        "github.com/charmbracelet/lipgloss"
        "github.com/muesli/termenv"
)

func main() {
        renderer := lipgloss.NewRenderer(os.Stdout, termenv.WithProfile(termenv.TrueColor))
        style := renderer.NewStyle().Foreground(lipgloss.Color("#FF0000")) // bright red
        fmt.Fprint(os.Stdout, style.Render("Hello, World!"))
}

Source Code
We have to explicitly do:

package main

import (
        "fmt"
        "os"

        "github.com/charmbracelet/lipgloss"
        "github.com/muesli/termenv"
)

func main() {
        renderer := lipgloss.NewRenderer(os.Stdout, termenv.WithProfile(termenv.TrueColor))
		renderer.SetColorProfile = termenv.TrueColor
        style := renderer.NewStyle().Foreground(lipgloss.Color("#FF0000")) // bright red
        fmt.Fprint(os.Stdout, style.Render("Hello, World!"))
}

Expected behavior
It should render in color.
