chore(nsq): bump version to 1.3.0

[iketiunn]

NSQ upgrade notes

This bumps the BeeInventor NSQ Helm chart from 1.2.7 to 1.3.0. The underlying NSQ app
image moves from nsqio/nsq:v1.2.1 to nsqio/nsq:v1.3.0.

Upstream NSQ v1.3.0 changelog highlights:

• Build/source maintenance: removes older gobindata / Go 1.16 support.
• nsqd: adds TLS root CA usage for nsqauth requests.
• nsqd: adds Unix socket listener support for TCP/HTTP/HTTPS.
• nsqd: adds /debug/freememory, richer /info, TLS 1.3 support, optional HTTP/HTTPS
  listener disabling, and related fixes.
• nsqadmin: updates frontend JS support to ES2020, adds paused-topic labeling, and fixes
  UI graph/counter issues.
• Bug fixes include Dockerfile cleanup, dependency updates, nsqd concurrency fixes, and
  statsd/memstats panic fixes.

Why no values changes

No values.yaml change is needed for this chart bump.

The chart already leaves image.tag unset, and the templates default the runtime image tag
from .Chart.AppVersion, so bumping appVersion to 1.3.0 automatically renders nsqio/ nsq:v1.3.0. Pinning image.tag in values would duplicate the same version and create
future drift risk.

The NSQ v1.3.0 changes are either build-time maintenance, bug fixes, or optional runtime
features behind new flags. Our existing chart values do not configure those optional flags,
and the current ports, services, lookupd wiring, persistence, replicas, and metrics settings
remain valid.
