Bumps the cargo group with 3 updates in the / directory: aws-sigv4, sha2 and tokio.

Changelog

Sourced from aws-sigv4's changelog.

New this release:

• 🐛 (client, smithy-rs#4921) Validate @hostLabel members are valid host labels. A @hostLabel value goes straight into the request authority, checked only by http::uri::Authority::from_str against the whole expanded prefix. That parser accepts a colon, and http::Uri then reads everything after it as an unparseable port and discards it. A label containing a colon therefore truncates the resolved host and drops the service suffix.

  The generated code now runs each host label through is_valid_host_label before building the prefix. Accepted labels narrow to [a-zA-Z0-9-]{1,63}. A value holding _ or . used to pass and now fails.

Breaking Changes:

• ⚠️🎉 (server, smithy-rs#4887, @​jeffzha) Add MetricsPool support to aws-smithy-http-server-metrics. The metrics layer now stores a SmithyMetricsPool producer handle in the request extensions. Independently-owned middleware and libraries that cannot name the service's metrics entry type can pull it out and contribute heterogeneous child metrics that flatten into the single per-request entry when the request finishes. Structs annotated with #[smithy_metrics] gain the backing pool automatically through a single hidden flattened field.

  This is a breaking change on two fronts.

  #[smithy_metrics] now injects a hidden __smithy_metrics field, so existing explicit struct literals no longer compile and __smithy_metrics is reserved as a field name. Construct these structs with ..Default::default() (or Default::default()) instead of naming every field:

  #[smithy_metrics]
  #[metrics]
  struct RequestMetrics {
      requests: u64,
  }
  fn new_metrics() -> RequestMetrics {
  RequestMetrics {
  requests: 1,
  ..Default::default()
  }
  }

  The default-metrics entry type was also renamed DefaultMetrics -> SmithyMetrics.
