fix: use semantic versioning for version comparisons in check-images-internal.ts

[Copilot]

String-based version comparison is unreliable for semantic versions. For example, "v8.5.10" <= "v8.5.3" incorrectly returns true because "1" < "3" lexicographically.

Changes

• Import @std/semver (already used elsewhere in this repo)
• Add normalizeVersion() to strip v prefix and -enterprise suffix
• Add versionGreaterOrEqual() and versionLessThanOrEqual() helper functions
• Replace all three string comparisons with semver-based comparisons

Example

// Before (buggy)
if (version <= "v8.5.3" && gitRepo === "pingcap/ticdc") { ... }

// After (correct)
if (versionLessThanOrEqual(version, "v8.5.3") && gitRepo === "pingcap/ticdc") { ... }

Hi @Copilot. Thanks for your PR.

I'm waiting for a PingCAP-QE member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dl.deno.land
  • Triggering command: /usr/bin/curl curl -s REDACTED (dns block)
• esm.sh
  • Triggering command: /usr/local/lib/node_modules/deno/deno /usr/local/lib/node_modules/deno/deno check check-images-internal.ts (dns block)
• jsr.io
  • Triggering command: /usr/local/lib/node_modules/deno/deno /usr/local/lib/node_modules/deno/deno check check-images-internal.ts (dns block)
  • Triggering command: /usr/local/lib/node_modules/deno/deno /usr/local/lib/node_modules/deno/deno run /tmp/semver-test.ts (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
