Add caseInsensitive field on string filters

[angrykoala]

Description

Add support for case insensitive string filters. These can be enabled with the option CASE_INSENSITIVE in features:

const neoSchema = new Neo4jGraphQL({
    features: {
        filters: {
            String: {
                CASE_INSENSITIVE: true,
            },
        },
    },
});

This enables the field caseInsensitive on string filters:

query {
    movies(where: { title: { caseInsensitive: { eq: "the matrix" } } }) {
        title
    }
}

This generates the following Cypher:

MATCH (this:Movie)
WHERE toLower(this.title) = toLower($param0)
RETURN this { .title } AS this

hey @angrykoala , just wondering wether this has been released? Since #6200 is merged I was assuming so, but #6250 is still open... I am confused :D

[angrykoala]

Hi @andreloeffelmann
Sorry for confusion, we had a conversation within the team about the desired API for case insensitive and a few questions about the API were raised. We want to address them before merging the feature, so it is now behind a feature flag (the PR #6250 removes that flag to enable the feature)

We want to make sure this new feature melds well with the new changes to the API v7 and doesn't require future breaking changes so we are taking it slow to make sure of that

The feature will probably be released mid may for version 7. Thanks for your patience 🙏
