Rename internal response

[Yang-33]

There is no issue with some variables conflicting, but not to confuse me, this change renames them.

for example, conflict is happened here:

line-bot-sdk-ruby/lib/line/bot/v2/messaging_api/api/messaging_api_blob_client.rb

Lines 192 to 228 in eb6780d

	def set_rich_menu_image_with_http_info(
	rich_menu_id:,
	body: nil
	)
	path = "/v2/bot/richmenu/{richMenuId}/content"
	.gsub(/{richMenuId}/, rich_menu_id)
	response = @http_client.post(
	path: path,
	body_params: body,
	)
	body = case response.code.to_i
	when 200
	response.body
	else
	response.body
	end
	[body, response.code.to_i, response.each_header.to_h]
	end
	# Upload rich menu image
	#
	# @param rich_menu_id The ID of the rich menu to attach the image to
	# @param body
	# @see https://developers.line.biz/en/reference/messaging-api/#upload-rich-menu-image
	def set_rich_menu_image(
	rich_menu_id:,
	body: nil
	)
	body, _status_code, _headers = set_rich_menu_image_with_http_info(
	rich_menu_id: rich_menu_id,
	body: body
	)
	body
