Chain name aliases

What is the current behavior?
Every chain has a unique network identifier, like mainnet, matic, xdai. Some of these chains were renamed but their unique identifier stayed the same. Eventually, new developers will be confused because they do not intuitively understand why a subgraph running on Polygon should have matic as network identifier. Same for xDai which was renamed to Gnosis Chain.

Though, just changing these network identifiers would break all existing subgraphs that still have matic as network and not polygon.

What is the expected behavior?

I would recommend to introduce network identifier aliases, so we can start to communicate the new names but still support the old ones.

Example:

matic -> polygon
xdai -> gnosis-chain

Etc.

Das Issue nennt keine Dateien, Tests oder Einstiegspunkte. Beginne damit zu ermitteln, wie graph-node Netzwerkkennungen validiert und verwendet, und verfolge dann die betroffenen Konfigurations- und Subgraph-Pfade. Als abgeschlossen gilt die Änderung, wenn umbenannte Kennungen wie polygon und gnosis-chain akzeptiert werden und bestehende matic- und xdai-Subgraphs weiterhin funktionieren.
