Describe your changes

I have added markdown rendering components to value and delta

It is functional like in the screenshot but I do not know how to deal with conflicting chars like - or $

I see 3 options:

1. add backslashes \ or back ticks ` to these values, so that they get disabled
2. add a new markdown enabled parameter to st.metric so that the user will have to choose if they want to have markdown behavior or not
3. add it like this with a hint for the user that he should use back ticks or backslashes when adding $

Please let me know what behavior is most desirable.

Code in my Screenshot:

st.metric(
    label="Temperature",
    value="70 °F $ **markdown**",
    delta=r"-1.2 °F \$ *markdown* $x^2 + y^2 = z^2$",
)

Screenshot or video (only for visual changes)
