test: [POM] Migrate connections e2e tests to TS and Page Object Model

[chloeYue]

Description

• Migrate connections e2e tests to TS and Page Object Model

test/e2e/tests/connections/edit-account-flow.spec.ts
test/e2e/tests/connections/edit-networks-flow.spec.ts

• Remove the spec test/e2e/tests/connections/connect-with-metamask.spec.js as it's already completely tested in another spec. We don't want to repeat testing.

• create more class methods for permission page class
