feat(query_builder): add orderByRandom

[RomainLanz]

Hey there! 👋🏻

This PR adds a orderByRandom method to retrieve records in a random order.
It defines the right keyword for each dialect.

The test may be flaky, I have set it up to run 3 times in case it fails.

A seed can be pass when using MySQL (same as Laravel implementation).

I am not sure how to deal with the mssql error. We are not passing multiple NEWID() to the order by clause. 🤔

It looks like it was reusing the same query builder, so it would carry over the previous order by.

I found that if you use a new query builder within the for loop, it works as expected:

Suggested change

	const db = getQueryBuilder(getQueryClient(connection))
	await getInsertBuilder(getQueryClient(connection))
	.table('users')
	.multiInsert([
	{
	username: 'virk',
	email: '[email protected]',
	},
	{
	username: 'romain',
	email: '[email protected]',
	},
	{
	username: 'nikk',
	email: '[email protected]',
	},
	])
	const userResults: number[][] = []
	for (let i = 0; i < 10; i++) {
	const result = await db.from('users').orderByRandom()
	userResults.push(result.map((user) => user.id))
	}
	const client = getQueryClient(connection)
	await getInsertBuilder(getQueryClient(connection))
	.table('users')
	.multiInsert([
	{
	username: 'virk',
	email: '[email protected]',
	},
	{
	username: 'romain',
	email: '[email protected]',
	},
	{
	username: 'nikk',
	email: '[email protected]',
	},
	])
	const userResults: number[][] = []
	for (let i = 0; i < 10; i++) {
	const result = await getQueryBuilder(client).from('users').orderByRandom()
	userResults.push(result.map((user) => user.id))
	}

Or clear the order by clauses like so:

const result = await db.from('users').clearOrder().orderByRandom()
