Rebuild Docker image to update dependencies

[ngosang]

I was doing a security scanner using Grype => https://github.com/anchore/grype
And I detected your Docker image has some outdated dependencies. I don't think they are a security risk but it's a good practice to publish releases more often. Thank you for your work!
