DLC-BTC. Remove filtering from vault fetching logic, add network support

[karen-stepanyan]

Closes DF-20315

Description

Fixed BTC vault fetching logic. Previously we filtered out placeholder values, but DLC.LINK team now recommends to fetch all the vault and skip the filtering.
Additionally added support for different networks. Currently the EA was deployed to Aribtirum and to deploy to a new chain, a new instance is needed as the config options supported one chain. PR includes changes so that different chains and RPCs can be provided.

Changes

• Removed the filter function from transport when fetching vault info
• Added support for new chains
• Replaced DLC_CONTRACT env variable with 'dlcContract' input parameter.
• Replaced RPC_URL, CHAIN_ID env variables with network-specific env variables ( {NETWORK}_RPC_URL, {NETWORK}_CHAIN_ID ).
• Added the EA to readme-generator blacklist as several config options are added to readme manually that are not part of config.ts

Steps to Test

yarn test packages/sources/dlc-btc-por/

Quality Assurance

• If a new adapter was made, or an existing one was modified so that its environment variables have changed, update the relevant infra-k8s configuration file.
• If a new adapter was made, or an existing one was modified so that its environment variables have changed, update the relevant adapter-secrets configuration file or update the soak testing blacklist.
• If a new adapter was made, or a new endpoint was added, update the test-payload.json file with relevant requests.
• The branch naming follows git flow (feature/x, chore/x, release/x, hotfix/x, fix/x) or is created from Jira.
• This is related to a maximum of one Jira story or GitHub issue.
• Types are safe (avoid TypeScript/TSLint features like any and disable, instead use more specific types).
• All code changes have 100% unit and integration test coverage. If testing is not applicable or too difficult to justify doing, the reasoning should be documented explicitly in the PR.

I would suggest to ignore the ea-framework dependency check until we figure out what to do
