[Task] Add version sorting, category filtering, and semantic versioning to Layout Templates

[maxcao13]

Describe the feature

Since cryostat 2.3 is the first release where Layout Templates have been introduced, there was no need for version sorting or categorization. Next version 2.4 will probably need this new feature in case card configurations change over time.

Every release, this also requires the versioning for user-submitted templates to increase according to the semantic versioning of Cryostat itself.

in dashboard-utils.tsx

export enum LayoutTemplateVersion {
  'v2.3' = 'v2.3',
}

Next release we will need to update this to

export enum LayoutTemplateVersion {
  'v2.3' = 'v2.3',
  'v2.4' = 'v2.4',
}

and templatize will need to be changed so that transformation can be done to user-submitted templates:

export const templatize = (layout: DashboardLayout, name: string, desc?: string): LayoutTemplate => {
  return {
    name: name,
    description: desc || `Custom layout template.`,
    cards: layout.cards.map((card) => {
      const { id: _id, ...cardWithoutId } = card;
      return { ...cardWithoutId };
    }) as SerialCardConfig[],
    vendor: LayoutTemplateVendor.USER,
    version: LayoutTemplateVersion['v2.4'], // change to 2.4!
  } as LayoutTemplate;
};

The cryostat-dashboard-templates versions should also probably be changed even if there are no changes for next release.
