feat!: Support both inline and secret-ref based auth for http file rules

[ahmad-ibra]

Issue

Resolves https://github.com/validator-labs/validator-plugin-network/issues/263

Description

• Adds an Auth struct which contains both a *BasicAuthSecretReference and a *BasicAuth
• Modifies Validate func to take in a map[string][]string instead of a [][][]byte. The key for the auth for each rule is the rule.Name(). This addresses a TODO thats found in validatorctl: https://github.com/validator-labs/validatorctl/blob/c7408a6254238c174deb005f4ac98c1ec2f25c99/pkg/components/validator.go#L450
