Cannot update a project with new tag names (that are not used already on the platform)

[dan-caprioara]

Current Behavior

If a tag was already attached to another project(tag T1 on project X), you can use the API to associate the tag T1 on project Y as well. But if you use the API to put a new tag T2 on project Y, it will fail with: "A tag with name T2 does not exist."

Steps to Reproduce

1. Use the Rest API to tag a project with a brand new tag name:

    @Path("/{name}/project")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    @Operation(
            summary = "Tags one or more projects.",
            description = "<p>Requires permission <strong>PORTFOLIO_MANAGEMENT</strong></p>"
    )````, it will call `org.dependencytrack.resources.v1.TagResource.tagProjects(String, Set<String>)`
   

2. An eror is obtained: "A tag with name T2 does not exist.""

Expected Behavior

The tag should be created automatically, persisted, and associated to the project, OR at least a REST API to properly create a tag should be provided. (By the way, please update the API descriptors, it looks like the API documentation is not updated)
org.dependencytrack.persistence.TagQueryManager.tagProjects(String, Collection)

        runInTransaction(() -> {
            final Tag tag = getTagByName(tagName);
            if (tag == null) {
              // TODO - CREATE HERE THE TAG,
                throw new NoSuchElementException("A tag with name %s does not exist".formatted(tagName));
            }

            final Query<Project> projectsQuery = pm.newQuery(Project.class);
            final var params = new HashMap<String, Object>(Map.of("uuids", projectUuids));
            preprocessACLs(projectsQuery, ":uuids.contains(uuid)", params, /* bypass */ false);
            projectsQuery.setNamedParameters(params);
            final List<Project> projects = executeAndCloseList(projectsQuery);

            for (final Project project : projects) {
                bind(project, List.of(tag), /* keepExisting */ true);
            }
        });
    }
