Replace deprecated retries option with timeout in rails 8 and above

[p-schlickmann]

Just another quick one to clean up the CI logs:

retries is deprecated in Rails 8.0 and will be fully removed in 8.1, so I replaced retries: 100 with timeout: 5000.

Why 5000? SQLite3Configuration#configure_connection sleeps count * 0.001 seconds on each retry, up to 100:
Σ(1..100) * 0.001 = 0.001 * 5050 ≈ 5.05s → ~5000ms. See:

solid_queue/test/dummy/config/initializers/sqlite3.rb

Lines 13 to 22 in 0ba1b7e

	def configure_connection
	super
	if @config[:retries]
	retries = self.class.type_cast_config_to_integer(@config[:retries])
	raw_connection.busy_handler do |count|
	(count <= retries).tap { |result| sleep count * 0.001 if result }
	end
	end
	end
