Add `renovate` to the new `allowed_bots` input

[lacolaco]

Claude Code Action v0.0.55 has new allowed_bots input to allow only trusted bots to invoke CLI.

• https://github.com/anthropics/claude-code-action/releases/tag/v0.0.55
• feat: add flexible bot access control with allowed_bots option anthropics/claude-code-action#117

# Allow specific trusted bots (recommended)
- uses: anthropics/claude-code-action@main
  with:
    allowed_bots: "dependabot,renovate"

# Allow all bots (use with caution in trusted environments)
- uses: anthropics/claude-code-action@main
  with:
    allowed_bots: "*"

# No bots allowed (default, most secure)
- uses: anthropics/claude-code-action@main
  # No allowed_bots parameter needed

By default, no bots are allowed. claude-renovate-review has to pass renovate to the input internally.

Thank you for opening this issue!

To clarify, claude-renovate-review directly uses anthropics/claude-code-action/base-action to bypass the permission checks implemented in anthropics/claude-code-action.

As far as I can see, the allowed_bots input is only an input used within anthropics/claude-code-action (it is not used in base-action), so it does not seem to affect claude-renovate-review at the moment.
