chore(release): 5.0.0-alpha.2 [skip ci]

# [5.0.0-alpha.2](https://github.com/parse-community/parse-server/compare/5.0.0-alpha.1...5.0.0-alpha.2) (2021-10-27)

### Bug Fixes

* setting a field to null does not delete it via GraphQL API ([#7649](https://github.com/parse-community/parse-server/issues/7649)) ([626fad2](626fad2e71))

### BREAKING CHANGES

* To delete a field via the GraphQL API, the field value has to be set to `null`. Previously, setting a field value to `null` would save a null value in the database, which was not according to the [GraphQL specs](https://spec.graphql.org/June2018/#sec-Null-Value). To delete a file field use `file: null`, the previous way of using `file: { file: null }` has become obsolete. ([626fad2](626fad2))
