[Playground CLI] skip-wordpress-setup overrides the mounted WordPress directory

[bgrgicak]

When I use the --skip-wordpress-setup argument with the Playground CLI (on trunk) it modifies the mounted WordPress directory by overriding WordPress files.

Steps to recreate

• Download WordPress and extract it to /MY-PATH/
• Modify one WordPress file
• Start Playground by mounting this directory

npx @wp-playground/cli@latest 
	server \
    --skip-wordpress-setup \
    --mount-before-install=/MY-PATH:/wordpress

• See that the WordPress file modification has been removed

Expected behavior

When WordPress is mounted before install in combination with --skip-wordpress-setup the mounted directory shouldn't be modified by Playgorund during boot.
