Add gitea topics

[wkelly17]

This adds in support for gitea topic.

They have their own table

export const gitTopic = pgTable(
  "git_topic",
  {
    id: serial("id").primaryKey(),
    name: varchar("name", {length: 128}).unique().notNull(),
  },
  (t) => [uniqueIndex("topic_name_idx").on(t.name)]
);

And then a pivot table:

  "repo_topic",
  {
    repoId: integer("repo_id")
      .references(() => gitRepo.id, {onDelete: "cascade"})
      .notNull(),

    topicId: integer("topic_id")
      .references(() => gitTopic.id, {onDelete: "cascade"})
      .notNull(),
  },
  (t) => [
    primaryKey({columns: [t.repoId, t.topicId]}),
    index("topic_idx").on(t.topicId),
  ]
);

And then the code for insertion is in bus-wacsevent-gitTopics.ts

There's a few dependency upgrades I went ahead and did in here as well.

For the query side, you can either go through the pivot table, or you can go through vw_consolidated_repos which I also exposed just as a rest api endpoint as well
