Progress component to support color_scheme on component level

[ElijahAhianyo]

This PR adds support for color_scheme on the progress bar component. Previously, you couldnt do this on the component itself, i.e the color scheme is always inherited globally, but with this PR you can.

class State(rx.State):
    indigo: str = "indigo"
    gray: str = "gray"

@rx.page()
def index():
    return rx.container(
        rx.flex(
            rx.progress(value=50, width="100%", color_scheme="mint"),
            rx.progress(value=60, width="100%", color_scheme="orange"),
            rx.progress(value=70, width="100%", color_scheme="grass"),
            rx.progress(value=80, width="100%", color_scheme="tomato"),

           # low level api
            rx.progress.root(
                rx.progress.indicator(
                    value=70,
                    max=100,
                    color_scheme="brown"
                )
            ),
            rx.progress.root(
                rx.progress.indicator(
                    value=30,
                    max=100,
                    color_scheme=State.gray
                )
            ),


            rx.progress(value=90, width="100%", color_scheme=State.indigo),
            rx.progress(value=100, width="100%"),
            direction="column",
        ),
)

# Add state and page to the app.
app = rx.App(
theme=rx.theme(
        has_background=True, radius="none", accent_color="green", appearance="light",
    ),
)
