remove html tag
This updates the doc with an appropriate curl command.
The docs currently warp the URL in an HTML tag:
curl \
--header "Content-Type: application/json" \
--request POST \
--data '{"GitLab":"FaaS"}' \
<http://functions-echo.functions-1.functions.example.com/>
Running this returns an error
-bash: syntax error near unexpected token
newline'`
Removing the html around the URL is the correct syntax for curl.
curl \
--header "Content-Type: application/json" \
--request POST \
--data '{"GitLab":"FaaS"}' \
http://functions-echo.functions-1.functions.example.com/
