[BUG] Bind mount file to file makes a file to directory

[Grasume]

Description

Working with someone in Discord and he noticed this issue. Was able to reproduce and cant find in the docs anymore where it specified file to file or folder to folder.

But when performing a simple bind mount like so volumes: - ./test/file.text:/test/file.text
the file.text becomes a diretory
if i just do the directory
volumes: - ./test/:/test/
is this supposed to be happening ? Did the ability to perform file to file bind mounts get removed ?

Steps To Reproduce

repo with simple folder structure https://github.com/Grasume/docker_example/tree/production/docker-compose-bindmount
docker compose up - d

docker-compose exec -it test sh

ls -l /test/ total 4 drwxr-xr-x 2 root root 4096 Nov 28 00:04 test.text

ls -l /test2/ total 4 -rw-rw-r-- 1 ubuntu ubuntu 19 Nov 27 23:54 test2.txt

Original file file.text does not exist in your example repo (but [test.txt](https://github.com/Grasume/docker_example/blob/production/docker-compose-bindmount/test/test.txt))
As a result, with a bind mount where source path does not exist, Docker engine standard behavior is to create source as a folder

Assuming this isn't a typo, you can control this behavior using create_host_path attribute, see https://docs.docker.com/reference/compose-file/services/#long-syntax-5
