packages: remove unmaintained javascript (#10613)

* packages: remove unmaintained javascript

This commit removes the following packages from the monorepo:
- `common-ts`
- `contracts-ts`
- `core-utils`
- `fee-estimation`
- `web3js-plugin`

These packages are not maintained. `chain-mon` and the `sdk` still
exist but are pending deprecation.

* readme: update

* mergify: leftover references

-## Contracts TS
-
-[![codecov](https://codecov.io/gh/ethereum-optimism/optimism/branch/develop/graph/badge.svg?token=0VTG7PG7YR&flag=contracts-bedrock-tests)](https://codecov.io/gh/ethereum-optimism/optimism)
-
-ABI and Address constants + generated code from [@eth-optimism/contracts-bedrock/](../contracts-bedrock/) for use in TypeScript.
-
-Much of this package is generated. See [CODE_GEN.md](./CODE_GEN.md) for instructions on how to generate.
-
-#### @eth-optimism/contracts-ts
-
-The main entrypoint exports constants related to contracts bedrock as const. As const allows it to be [used in TypeScript with stronger typing than importing JSON](https://github.com/microsoft/TypeScript/issues/32063).
-
-- Exports contract abis.
-- Exports contract addresses
-
-```typescript
-import {
-  l2OutputOracleProxyABI,
-  l2OutputOracleAddresses,
-} from '@eth-optimism/contracts-ts'
-
-console.log(l2OutputOracleAddresses[10], abi)
-```
-
-Addresses are also exported as an object for convenience.
-
-```typescript
-import { addresses } from '@eth-optimism/contracts-ts'
-
-console.log(addresses.l2OutputOracle[10])
-```
-
-#### @eth-optimism/contracts-ts/react
-
-- All [React hooks](https://wagmi.sh/cli/plugins/react) `@eth-optimism/contracts-ts/react`
-
-```typescript
-import { useAddressManagerAddress } from '@eth-optimism/contracts-ts/react'
-
-const component = () => {
-  const { data, error, loading } = useAddressManagerAddress()
-  if (loading) {
-    return <div>Loading</div>
-  }
-  if (err) {
-    return <div>Error</div>
-  }
-  return <div>{data}</div>
-}
-```
-
-#### @eth-optimism/contracts-ts/actions
-
-- All [wagmi actions](https://wagmi.sh/react/actions) for use in Vanilla JS or non react code
-
-```typescript
-import { readSystemConfig } from '@eth-optimism/contracts-ts/actions'
-console.log(await readSystemConfig())
-```
