2024-04-02 missing port-mapping quotes - master branch - PR 1 of 2

Following on from discussion in #761, this adds quotes to port mappings
as recommended in docker-compose
[documentation](https://docs.docker.com/compose/compose-file/05-services/#short-syntax-3):

> HOST:CONTAINER should always be specified as a (quoted) string, to
avoid conflicts with
[yaml base-60 float](https://yaml.org/type/float.html)
