Entrypoint error when running app-start.sh

[alex-atkins]

Describe the bug
Getting the following error when trying to run app-start.sh:

env: can't execute 'bash
': No such file or directory

Looks like it is coming from here:

unstructured-api/scripts/app-start.sh

Line 1 in 2a0f3b7

#!/usr/bin/env bash

To Reproduce
Tag: 0.0.80
Build Dockerfile: make docker-build.sh
note: had to modify because there is a \r line separator that needs to be removed. Check for this in app-start.sh, but doesn't seem to be the issue.
Start app: make docker-start-api
Get error:
': No such file or directory
Note: Also entered container with make docker-start-bash and ran scripts/app-start.sh with same error.

Environment:

• Build Env: Windows 11, MINGW64 terminal; Also tested on WSL2 Ubuntu with same results

Additional context
I see a similar issue #261 referencing a whitespace, but that is not present here.

There's some hidden value on the new line below. Removing the empty line and recreating it fixes the problem. There seems to be a line separator or other hidden character in a lot of these .sh files that causes issues in certain environments. Is there a way to remove them all and make sure future commits are clean?
