ci: skip contributor template check for renovate-bot's User account

[Yicong-Huang]

What changes were proposed in this PR?

The contributor-checks job in .github/workflows/contributor-checks.yml gates on github.event.sender.type != 'Bot' so it won't nag automated PR/issue openers about not following the contribution template.

That gate catches GitHub App bots (e.g. dependabot[bot], whose account type is Bot) but not Renovate, which on this repo runs under a regular User account: renovate-bot has type: User, so it slips through and gets the "the description doesn't follow our template" warning on every dependency-update PR (example: #7060).

This PR excludes renovate-bot explicitly by login:

if: >-
  github.event.sender.type != 'Bot' &&
  github.event.sender.login != 'renovate-bot'

Any related issues, documentation, discussions?

Closes #7063.

Example of the false warning: #7060.

How was this PR tested?

• Confirmed via the GitHub API that renovate-bot has type: User (not Bot), which is why the existing sender.type != 'Bot' gate did not exclude it.
• Validated the workflow YAML parses and the folded if: expression resolves to the intended single-line condition.
• The change is confined to the job-level if: gate; no run: step or untrusted-input interpolation is touched.
