Unify the publisher for VS Code Marketplace & Open VSX

[mingxuanzhangsfdx]

Describe the bug
Hi there! This is from Salesforce VS Code team. apex-pmd is part of Salesforce VS Code Expanded Pack. We recently found a discrepancy of the entries for apex-pmd in Open VSX and VS Code Marketplace. In VS Code Marketplace it is chuckjonas.apex-pmd whereas in Open VSX Registry it is pmd.apex-pmd.

apex-pmd is the only extension within the expanded pack has the different entries for Marketplace and Open VSX Registry. We only publish a single version of expanded pack, so that makes the installation from Open VSX unable to find apex-pmd previously. We just checked in a fix but that is kind of an undefined behavior of VS Code - VS Code does not report any warnings or errors if the entry is not existed. We are still hoping apex-pmd could have a unified publisher.

Looking forward to your reply!
