Add downloads by package manager over time to the main page

[DamianMaslanka5]

Some time ago I looked for similar information and I was not able find any data which clearly shows how popular uv really is.
Stars on github don't always translate into real world usage.

I think this chart might be useful for other people deciding if they should replace pip with uv

Current sql query is slow (10s), so new table only for this query is needed.

SELECT toStartOfWeek(date) AS x, installer AS name, sum(count) AS y
FROM pypi.pypi_downloads_per_day_by_version_by_installer_by_type
WHERE date > toStartOfMonth(now() - toIntervalMonth(18)) and x != toStartOfWeek(now()) AND installer IN ('pip', 'uv', 'poetry')
GROUP BY x, name
ORDER BY x ASC

New table

CREATE OR REPLACE TABLE pypi.pypi_downloads_per_day_by_installer
(
    `date` Date,
    `installer` String,
    `count` Int64
)
ENGINE = SummingMergeTree
ORDER BY (date, installer)
