Field possibly erroneously set as `Schema.RequiredMode.REQUIRED`

[cardamon]

Current Behavior

dependency-track/src/main/java/org/dependencytrack/model/RepositoryMetaComponent.java

Lines 84 to 90 in 626a0cb

	/**
	* The optional date when the component was last published.
	*/
	@Persistent
	@Column(name = "PUBLISHED")
	@Schema(type = "integer", format = "int64", requiredMode = Schema.RequiredMode.REQUIRED, description = "UNIX epoch timestamp in milliseconds")
	private Date published;

Comment says it's optional and from a quick search through the code base it appears to indeed be conditionally set, not set at all, etc.

This may cause issues for generated OpenAPI clients which assume that the field is always set.

Steps to Reproduce

An API call to /v1/repository/latest may return data such as:

{
    "repositoryType": "NPM",
    "name": "buffer",
    "latestVersion": "6.0.3",
    "lastCheck": 1775555220982
}

in which published is absent.

Expected Behavior

Either published to always have some value (0?) or, for it not be set as required.
