Starship: Convert to modify-template to avoid overwrite prompts

A second chezmoi layer modifies these files after this layer writes
them, causing chezmoi to detect a conflict and prompt on the next
apply. Using modify-template makes chezmoi treat the files as
transformations rather than managed files, avoiding the prompt.
