Depend on remote artifacts for mantis-shaded instead of local subproject

[hmitnflx]

Context

Currently, we depend on the local copy of jar (subproject) for mantis-shaded dependency. However, this leads to problems with IntelliJ where you have to manually add the mantis-shaded subproject as an explicit library dependency at the root OR deal with a bunch of redlines for these shaded components.

We tried a bunch of alternatives like publishing to local maven or including these shaded dependencies at the terminal level (leaf projects) and they open-up more issues. We decided to host mantis-shaded in a separate repo but we think this could be a better alternative
