packaging/docs: replace deprecated rpc.batchlimit key

[odupontt]

Description

This PR fixes a real configuration correctness issue caused by a key mismatch between runtime config parsing and shipped templates/docs.

internal/cli/server/config.go now expects rpc.batch-request-limit, but multiple template files and the CLI example still used rpc.batchlimit.
If operators uncommented the old key, Bor silently ignored it and kept the default batch request limit (1000), which could lead to unexpected production behavior.

What was done:

1. Replaced rpc.batchlimit with rpc.batch-request-limit in all affected packaging templates.
2. Updated builder/files/config.toml to use the correct key.
3. Updated docs/cli/example_config.toml to keep docs/examples aligned with runtime behavior.
4. Kept the change minimal: key rename only, no default value changes, no runtime logic changes.

Changes

• Bugfix (non-breaking change that solves an issue)
• Hotfix (change that solves an urgent issue, and requires immediate attention)
• New feature (non-breaking change that adds functionality)
• Breaking change (change that is not backwards-compatible and/or changes current functionality)
• Changes only for a subset of nodes

Nodes audience

This change applies to all operators who rely on shipped Bor templates/examples.
It is not limited to a subset of nodes.

Manual tests

1. Verified old key is removed from repo templates/examples:
   • rg -n "rpc\.batchlimit" .
   • Result: no matches in templates/docs after this PR.
2. Verified new key is present where expected:
   • rg -n "rpc\.batch-request-limit" builder packaging docs
   • Result: matches found across updated template/example files.
3. Confirmed scope is limited to template/docs key rename via diff review.

Additional comments

No runtime code path or default value was changed in this PR; this is a template/docs correctness alignment fix to prevent silent misconfiguration.
