ERC-4337 Bundler Updates

[nlordell]

This PR updates the reference bundler used for E2E tests:

• It uses a newer version of the bundler that includes the exception to associated storage access for staked factories (rule fix: allow account to access associated storage if factory is staked eth-infinitism/bundler#127).
• Uses the --auto flag; by default, the bundler will wait for whichever comes first of 3 second or 10 user operations before submitting a bundle, with --auto flag, it submits the bundle right away

Notice that the E2E test run significantly faster with this change:

# before
  E2E - Local Bundler
    ✔ should deploy a new Safe and execute a transaction (3731ms)
    ✔ should execute a transaction for an exsiting Safe (2880ms)
# after
  E2E - Local Bundler
    ✔ should deploy a new Safe and execute a transaction (912ms)
    ✔ should execute a transaction for an exsiting Safe (628ms)
