Description of your changes

User can use alias metadata in cue.

Fixes #

I have:

• Read and followed KubeVela's contribution process.
• Related Docs updated properly. In a new feature or configuration option, an update to the documentation is necessary.
• Run make reviewable to ensure this PR is ready for review.
• Added backport release-x.y labels to auto-backport this PR if necessary.

How has this code been tested

go run cmd/plugin/main.go def render test.cue
go run cmd/plugin/main.go def get test-trait

test: {
	type:  "trait"
	alias: "可以加上中文别名"
}

Special notes for your reviewer

The alias field can also be placed in the annotation, but I think it's better as a native field.

let's align the key with where it's used

[zhiyu0729]

lost in cli args, fixed.

[wonderflow]

does velaux apiserver use this alias? @barnettZQG

[zhiyu0729]

currently not, but we can use it later

[wonderflow]

It should be used somewhere or it's meanless.

[Somefive]

Is this alias used in any other places? Like vela def list? Or kubectl get TraitDefintion?

[zhiyu0729]

We're currently using aliases to show our preferred naming on ux instead of dns-formatted english, which is a great experience.

Yes, you can also give that experience in vela def list , vela trait, and vela component.

Okay, I recommend to make this alias also available in vela def list, vela trait and other related commands. But it does not necessarily to be done in this PR. We can leave it for future work.

[zhiyu0729]

Yes, it can also be used in vela def get or list, but I'm not sure if there is such a case, maybe we can add when needed
