[API v4] "Create project": Tags parameter is missing in the API

@markglenfletcher

1.Without Tags: successfull API call

git_repository_description="This is a test"
# Replacing all reserved characters by percent encoded ones in string variable
git_repository_description=$(http-encode-url.sh "$git_repository_description")

curl --request POST --header "PRIVATE-TOKEN: ${GITLAB_API_PRIVATE_TOKEN}" "https://gitlab.com/api/v4/projects?name=Test1&issues_enabled=true&visibility=private&description=${git_repository_description}"

2.With Tags: dismissed tags in the API response

git_repository_description="This is a second test"
git_repository_tags="tags, test2"
# Replacing all reserved characters by percent encoded ones in string variables
git_repository_description=$(http-encode-url.sh "$git_repository_description")
git_repository_tags=$(http-encode-url.sh "$git_repository_tags")

curl --request POST --header "PRIVATE-TOKEN: ${GITLAB_API_PRIVATE_TOKEN}" "https://gitlab.com/api/v4/projects?name=Test2&issues_enabled=true&visibility=private&description=${git_repository_description}&tag_list=${git_repository_tags}"

As you can see, the "tag_list" is empty in the response and in the API documentation, but present on the browser project settings page in a manually created project:
