Geo - Support filtering pages deployment by keyword via GraphQL

What does this MR do and why?

Currently, for self-service replicables, we are unable to do any filtering on the Geo Replicable views.

This MR supports filtering pages deployment registries by keyword (fuzzy_search) via GraphQL:

Registry	Searchable attributes
Pages Deployments	File

Database

Raw SQL and query plans

Using:

PagesDeployment.search('filename123')

Then:

https://console.postgres.ai/gitlab/gitlab-production-tunnel-pg12/sessions/15094/commands/52483

SELECT
    pages_deployments.*
FROM
    pages_deployments
WHERE
    pages_deployments.file ILIKE '%filename123%';

Query plan (without index):
