Naga add hardcoded keysets

[GTC6244]

Description

1. Updates to the latest develop build of networkContext.json to catch keysets. Adds a hardcoded naga-keyset1 value, since this is the coding in lit-node right now.

2. Adds a LICENCE file for the wasm package ( suppresses a warning! )

3. Removes wasm-opt for the release build of the wasm package. Might be a local descrepency.

Type of change

• [X ] New feature (non-breaking change which adds functionality)

This is blocked until naga-dev, naga-staging and naga-test are deployed, as we will hit the Missing or invalid parameters error for the mintNextAndAddAuthMethods ABI method when testing against the live networks

This PR has been tested locally but not against a live network

[Ansonhkg]

naga-dev is now up and ready to be tested against.

We will be using this branch to release a naga-dev beta instead of the naga main branch until all live networks are deployed with the keyset change.

Or, we could add an optional network-specific overrides to handle this kindda thing, but that's another topic.

My apologies @GTC6244 @DashKash54

This PR was accidentally merged as the same time when I merged this pr #877 (to fix the types) to the naga main branch.

I will create a new branch and re-add the changes for this branch, will update here.
