Make route conform to HTTP standard

[Naapperas]

Since this is a GET request:

nijobs-be/src/api/routes/company.js

Lines 203 to 218 in b6e70aa

	router.get("/:companyId/hasReachedMaxConcurrentOffersBetweenDates",
	or([
	authMiddleware.isCompany,
	authMiddleware.isAdmin,
	authMiddleware.isGod,
	], { status_code: HTTPStatus.UNAUTHORIZED, error_code: ErrorTypes.FORBIDDEN, msg: ValidationReasons.INSUFFICIENT_PERMISSIONS }),
	validators.checkConcurrent,
	validators.setDefaultValuesConcurrent,
	(req, res, next) => companyMiddleware.canManageAccountSettings(req.params.companyId)(req, res, next),
	async (req, res, next) => {
	try {
	const maxNotReached = await concurrentOffersNotExceeded(Offer)(
	req.params.companyId,
	req.body.publishDate,
	req.body.publishEndDate
	);

any data passed in should come from the query. There are other matters such as making the endpoint idempotent (not sure if it is already) but that is the main one.
