Theming: Unable to change text input placeholder color

[b0o]

Description

It seems none of the theme keys apply to the placeholder text in input fields:

If I create a custom theme where each color is set to #00FF00, the placeholder text is the only element that is unchanged:

Same with the command palette:

All-Green Theme

This issue might be a duplicate of existing issues. Please check:

• #4461: Input text is black on black (similar issue with input text styling and visibility)
• #4928: Diffs invisible on light mode (related to theme colors not applying to certain UI elements)
• #4551: Code Formatting for light themes does not correctly (related issue with text styling in light themes)

Feel free to ignore if none of these address your specific case.

Proposal: how about we add placeholderText as a new, optional theme field to control the colour of placeholder text, falling back to the existing textMuted property if the placeholderText field is not present in the theme?
