Fix AppData computation

[fleupold]

After #33, the existing code would generate a newer version of the app data

{"appCode":"CoWFeeModule","environment":"prod","metadata":{},"version":"1.3.0"}
vs
{"appCode":"CoWFeeModule","environment":"prod","metadata":{},"version":"1.1.0"}

which consequently led to this error being hit. @alfetopito suggested to manually generate the app data, given that it's hardcoded and fixed in the fee withdrawl module

Other changes

I had to change the target of the tsconfig to es2022 because es2023 is not supported by my node version (lts, v22.13.0)

I'd also say we should do this, it'd be less confusing than using a frozen version of the current app data and it would be overall simpler.

Just to confirm, this is what this PR does, or do you have something different in mind? I'd still like to send the app data content in plain text to the backend (so we don't have to manually register the hash if we deploy on a new chain).

The changes look good and can be merged.

I was thinking of having appDataHex and appDataContent as global constants instead of using metadataApi.appDataToCid. These constants could even be used in the deployment script: the service in this repo requires some specific app data anyway, so we don't want to allow changing it.

This is something we maybe should do as part of the deployment script. We somewhat need to do it anyway for simplicity of reviewing the transaction enabling the module (see example comment here).

This makes sense (one less thing to configure when deploying). I will leave this untackled here though as it seems somehwat low priority.
