Check when @id is suggested and fix

[Jolg42]

@tomhoule found someething by reading the code during a review and it seems that we are too strict for when we suggest @id

Code

language-tools/packages/language-server/src/completion/completions.ts

Lines 286 to 289 in 8f24706

	if (!(currentLine.includes('Int') || currentLine.includes('String'))) {
	// id not allowed
	suggestions = suggestions.filter((sugg) => sugg.label !== '@id')
	}

Bytes and BigInt are common for PKs, and other types work too.

Docs https://www.prisma.io/docs/reference/api-reference/prisma-schema-reference#id

Can be defined on any scalar field (String, Int, enum)
Cannot be defined on a relation field

@tomhoule so here I'll check to add it for enum and see if it's suggested on relation fields, anything else to check?
