Osu-web: All beatmaps of set ID 356821 seem to have wrong computed checksum

[frenzibyte]

According to my understanding, beatmap checksums are MD5 hashes computed based on the content of the .osu file, which is correct checking with every single beatmap, but the beatmaps of set ID 356821, all checksums provided by them (via room querying API request) do not match with what they were expected to be, here's a table showing off the provided checksums and the expected checksums:
| Beatmap ID | Checksums provided by room querying request | Expected checksum (MD5 hash of .osu file content) |
|:------------:|:-----------------------------------------------:|:------------------------------------------------------:|

This issue causes these beatmaps to be unplayable in multiplayer rooms osu!lazer-side due to the checksum mismatches above.

The .osu files inside the .osz don't match the latest versions provided by the server (you can check these via https://osu.ppy.sh/osu/<beatmap_id>.

We'll push a fix for the outdated osz to fix this instance.

This is fixed.
