fix error `Couldn't open file /codekarma/src/main.ts`

[ltfschoen]

if you follow the README instructions by following these steps:

• Install Docker
• Build Docker container from image

export DOCKER_DEFAULT_PLATFORM=linux/amd64
./docker/build.sh

• Run Docker container

./docker/run.sh

• Enter shell of Docker container

docker exec --user root -it ltfschoen-ethberlin04 /bin/bash

./bin/act --container-options \"--privileged\" --workflows '.github/workflows/dev.yml' -j 'run' --json --platform ubuntu-18.04=nektos/act-environments-ubuntu:18.04 --watch

It outputs the following error in the logs even though the file /codekarma/src/main.ts is clearly there

{"dryrun":false,"job":"dev/run","jobID":"run","level":"info","matrix":{},"msg":"curl: (37) Couldn't open file /codekarma/src/main.ts\r\n","raw_output":true,"stage":"Main","step":"Detect and report non-compliance with manifest or plugin registry","stepID":["3"],"time":"2024-05-26T07:55:52Z"}
