Does this issue occur when all extensions are disabled?: Yes

Version: 1.93.1 (user setup)

Steps to Reproduce:

1. Pick any theme
2. set "workbench.colorCustomizations": { "editor.placeholder.foreground": "#ff0000"}
3. expected: placeholder text of git commit message should turn red (or to any color you set) - but actually it stays the default which is "editorGhostText.foreground". Changing the ghost text color indeed also changes this placeholder text color.

I checked using the developer tool that the placeholder text of git commit message is indeed controlled by editor.placeholder.foreground.
