FI-705 fix: stricter type of expect function

fix: support usual promises in `expect` function
feat: add field `maxIntervalBetweenRequestsInMs` ot abstract class `Page`
feat: add examples of `mapBackendResponseErrorToLog`/`mapBackendResponseToLog`
tests: more tests of types of selectors methods
chore: update nodejs to current LTS (20.10.0)
chore: update alpine to 3.18.5
fix: support new contributor in `updateChangelog` script
refactor: move selectors code to `utils/selectors`
refactor: remove `utils/locators`
fix: use default cursor for empty expanded steps
feat: add duration to backend response logs
refactor: rename function `it` to `test` in initial autotests examples
fix: print `message` and `cause` fields of `E2edError` in `replaceFields`
fix: reject stuck assertion of `expect` by timeout
tests: add separate tests for `expect` function
feat: add type `ResponseWithRequest` to public API
feat: use `ResponseWithRequest` for mapping backend responses to logs
chore: update devDependencies (typescript, eslint, @types/node, etc)
chore: update npm `lockfileVersion` (package-lock.json) from 2 to 3
