Update Dockerfile (#2342)

Updates/adds a new multistage (build-kit) Dockerfile. (if accepted, could make `Dockerfile.monolith` and `Dockerfile.polylith` in `build/docker` obsolete) There's no huge difference between the dockerfiles, except this uses a non-root user when running the container, also doesn't copy the working directory to the image when building. Also adds vulnerabilities scans using [Trivy](https://github.com/aquasecurity/trivy) for the created docker images. (untested) Building images is done using ``` docker build . --target image-monolith -t dendrite-monolith docker build . --target image-polylith -t dendrite-polylith ``` As noted in the comments, only adds `dendrite-polylith-multi` to the polylith image and all required binaries to the monolith image. Probably needs some docs updating, if this is accepted. Co-authored-by: Neil Alexander <neilalexander@users.noreply.github.com>

 ## Dockerfiles

-The `Dockerfile` builds the base image which contains all of the Dendrite
-components. The `Dockerfile.component` file takes the given component, as
-specified with `--buildarg component=` from the base image and produce
-smaller component-specific images, which are substantially smaller and do
-not contain the Go toolchain etc.
+The `Dockerfile` is a multistage file which can build all three Dendrite
+images depending on the supplied `--target`. From the root of the Dendrite
+repository, run:
+
+```
+docker build . --target monolith -t matrixdotorg/dendrite-monolith
+docker build . --target polylith -t matrixdotorg/dendrite-monolith
+docker build . --target demo-pinecone -t matrixdotorg/dendrite-monolith
