build(deps): bump joi and express-joi-validation

[halfwhole]

Problem

With npm v8 install, the --legacy-peer-deps flag is necessary because of conflicting peer dependencies, and we'd like to get rid of this flag by resolving the peer dependency conflicts.

One of these conflicts is between express-joi-validation and @hapi/joi. express-joi-validation is at 4.0.3 which wants @hapi/joi at 16 as a peer dependency, but @hapi/joi is currently 17 which is incompatible.

Solution

Upgrade express-joi-validation to the latest which is 5.0.1, and upgrade @hapi/joi from 17.1.1 to the latest joi at 17.7.0 (@hapi/joi has been deprecated in favour of joi). These latest versions of express-joi-validation and joi are compatible as peer dependencies.

(There are other remaining peer deps conflicts to resolve, so we can't get rid of --legacy-peer-deps just yet.)

Tests

• Tested on staging, all looks fine
