Support deployment on Sepolia (#3706)

The Görli testnet currently used by Threshold/Keep for development
purposes is planned to become deprecated with the end of year 2023. The
testnet that is planned to replace it is called
[Holešky](https://github.com/eth-clients/holesky), however it's not yet
available - it's planned it will become widely accessible on Oct 1, 2023
([source](https://everstake.one/blog/new-ethereum-testnet-holesky-all-you-need-to-know-now)).
Switching our infrastructure to support new testnet is quite time
consuming, so moving directly from Görli to Holešky may be quite risky,
especially if there would be some delays in the date of Holešky genesis
(not meeting the planned timelines is not a rare occurrence in the
Ethereum space). As a solution, we decided to switch first to another
testnet that is currently live - Sepolia. This testnet's EOL is planned
for 2026, which gives us plenty of time to move to Holešky before
Sepolia gets deprecated.
