chore(deps): update schemars requirement from 0.8 to 1.2

[dependabot]

Updates the requirements on schemars to permit the latest version.

Release notes

Sourced from schemars's releases.

v0.8.22

Fixed:

• Fix compatibility with rust 2024 edition (GREsau/schemars#378)

Changelog

Sourced from schemars's changelog.

[0.8.22] - 2025-02-25

Fixed:

• Fix compatibility with rust 2024 edition (GREsau/schemars#378)

[1.0.0-alpha.17] - 2024-12-02

Changed

• For newtype variants of internally-tagged enums, prefer referencing the inner type's schema via $ref instead of always inlining the schema (GREsau/schemars#355) (this change was included in the release notes for 1.0.0-alpha.16, but was accidentally excluded from the published crate)

[1.0.0-alpha.16] - 2024-11-25

Removed (⚠️ breaking changes ⚠️)

• the enumset1/enumset optional dependency has been removed, as its JsonSchema impl did not actually match the default serialization format of EnumSet (GREsau/schemars#339)

Changed (⚠️ breaking changes ⚠️)

• MSRV is now 1.70
• The example attribute value is now an arbitrary expression, rather than a string literal identifying a function to call. To avoid silent behaviour changes, the expression must not be a string literal where the value can be parsed as a function path - e.g. #[schemars(example = "foo")] is now a compile error, but #[schemars(example = foo())] is allowed (as is #[schemars(example = &"foo")] if you want the the literal string value "foo" to be the example).

Fixed

• The "deserialize" schema for bytes::Bytes/BytesMut now allows strings, matching the actual deserialize behaviour of the types.
• The schema for either::Either now matches the actual serialize/deserialize behaviour of that type.

[1.0.0-alpha.15] - 2024-09-05

Added

• SchemaSettings now has a contract field which determines whether the generated schemas describe how types are serialized or deserialized. By default, this is set to Deserialize, as this more closely matches the behaviour of previous versions - you can change this to Serialize to instead generate schemas describing the type's serialization behaviour (GREsau/schemars#48 / GREsau/schemars#335)

Changed

• Schemas generated for enums with no variants will now generate false (or equivalently {"not":{}}), instead of {"enum":[]}. This is so generated schemas no longer violate the JSON Schema spec's recommendation that a schema's enum array "SHOULD have at least one element".

[1.0.0-alpha.14] - 2024-08-29

Added

• Read #[garde(...)] attributes as an alternative to #[validate(...)] (GREsau/schemars#233 / GREsau/schemars#331). See the documentation for a full list of supported attributes.

[1.0.0-alpha.13] - 2024-08-27

Fixed

• Fix compile errors when using #[validate(regex(path = *expr))] attribute
