add support for OpenJDK Early Access builds

Possible downsides?

Early Access builds should really only be used for experimentation at the moment. However it may be generally advantageous to have this pattern available for future EA builds from OpenJDK projects (e.g. Valhalla or any as-yet-unreleased OpenJDK build, which could be used for prototyping before features land in a full JDK release).

Generate changelog in changelog/@unreleased

What do the change types mean?

• feature: A new feature of the service.
• improvement: An incremental improvement in the functionality or operation of the service.
• fix: Remedies the incorrect behaviour of a component of the service in a backwards-compatible way.
• break: Has the potential to break consumers of this service's API, inclusive of both Palantir services
  and external consumers of the service's API (e.g. customer-written software or integrations).
• deprecation: Advertises the intention to remove service functionality without any change to the
  operation of the service itself.
• manualTask: Requires the possibility of manual intervention (running a script, eyeballing configuration,
  performing database surgery, ...) at the time of upgrade for it to succeed.
• migration: A fully automatic upgrade migration task with no engineer input required.

Note: only one type should be chosen.

How are new versions calculated?

• ❗The break and manual task changelog types will result in a major release!
• 🐛 The fix changelog type will result in a minor release in most cases, and a patch release version for patch branches. This behaviour is configurable in autorelease.
• ✨ All others will result in a minor version release.

i think this might still need some tweaking to allow the base URL to be correctly overridden in certain scenarios

[CRogers]

Rather than loom EA specifically, can we just have one for all OpenJDK EAs (and have loom in the version string?)

[CRogers]

Looks like it is in the version string? 24-loom+7-60

[bjlaub]

Yeah I think I can make this work. The URLs are ever so slightly different for e.g. JDK24 EA builds versus project-specific builds, but I think we can work around that.

@CRogers i think e0fb0db should do the trick
