up sdk and intl

[alex-relov]

Hello! After upgrade flutter SDK to 3.22 a have problems with my dependencies:

Resolving dependencies...
Note: intl is pinned to version 0.19.0 by flutter_localizations from the flutter SDK.
See https://dart.dev/go/sdk-version-pinning for details.

Because humanizer >=2.1.0 depends on intl ^0.18.0 and every version of flutter_localizations from sdk depends on intl 0.19.0, humanizer >=2.1.0 is incompatible with flutter_localizations from sdk.
And because every version of auth_lib depends on flutter_localizations from sdk, humanizer >=2.1.0 is incompatible with auth_lib.

In this pr I update intl to 0.19.0. This should solve the problem

Bump. Unless people use dependency overrides, this can be breaking for apps trying to upgrade. FWIW, the changes look fine to me.
