Bump harvester-load-balancer to v0.2.5

[w13915984028]

To fix harvester/harvester#5137, the harvester-load-balancer image has a new v0.2.5 release.

Bump a new chart v0.2.5 release to Harvester.

[w13915984028]

This PR looks to be redundant, unless the chart itself is changed, new commits to controller master-head will be auto fetched by the new ISO.

@bk201 please help double confirm, thank.

Refer: harvester/harvester#5137 (comment)

///
After PR harvester/load-balancer-harvester#26 is merged, a new master-head image of harvester-load-balancer is built.

The harvester/harvester-installer will always use the master-head image of harvester-load-balancer to build-iso. With a latest local build ISO, the issue is verifyed to be solved.

Yes, you are correct. If a chart doesn't change, we just need a PR to bump the image tag in release branches: https://github.com/harvester/harvester/blob/f8469881441b92a71c6e58a493f433eccf5f3ba1/deploy/charts/harvester/values.yaml#L458, can you help create a PR for it? Thanks.

Bumping a chart when its image changes is also OK, but it is only useful when you use the chart without harvester or for testing/dev purposes.

Just one nit, else LGTM. Thank you.

The image tag defaults to the chart appVersion, so we can drop the explicit version string unless we need something else here.

Suggested change

	tag: v0.2.5
	tag: ""

The harvester-load-balancer chart is not used out of Harvester cluster. Instead of releasing a new chart version, just bump the image tag in Harvester v1.3 branch.
