chore: pin Grafana version in docker-compose.yml

[shekhirin]

When dashboard is exported, it has a Grafana version specified:

reth/etc/grafana/dashboards/overview.json

Lines 26 to 31 in 80ee49b

	{
	"type": "grafana",
	"id": "grafana",
	"name": "Grafana",
	"version": "10.1.0"
	},

To both prevent breaking changes and unwanted version bumps in dashboard JSON, pin the Grafana version in docker-compose.yml file.
