Add Quesma to main integration page.

[jakozaur]

Quesma is not visible on page: https://clickhouse.com/integrations

Though it is visible on page: https://clickhouse.com/docs/en/integrations As we added it previously using: https://github.com/ClickHouse/clickhouse-docs/pull/2410

This confused some potential users, who did not find this use case viable.

What is the process to be also present on the: https://clickhouse.com/integrations ?
