docs(changelog): quote mysql-* prefixes and credit the snmp #986 contributor

Bare "mysql-*" let Markdown read the asterisk as emphasis; wrap it in
backticks consistently across the file. Also add the "thanks to" credit
for the snmp perfdata min/max entry.

 ### Fixed
 
@@ -36,7 +36,7 @@ Monitoring Plugins:
 * about-me: "User-Installed Software" table (renamed from the misleading "Non-default Software") now lists every package instead of just the first one
 * all plugins: importing `lib.url` on RHEL 8's default `python3` (3.6) no longer aborts with `AttributeError: module 'ssl' has no attribute 'TLSVersion'`. Plugins that don't use TLS version pinning keep working; calls that pin TLS get a clearer error. Officially supported minimum stays Python 3.9 (fix shipped via `linuxfabrik-lib` 4.0.2)
 * fail2ban: a banned jail no longer mislabels the following jails with its state in the output
-* mysql-*: queries against `mysql.user` and `mysql.global_priv` no longer abort with "Illegal mix of collations" when the server's connection-collation default differs from the system tables' column collations. Fix lives in `linuxfabrik-lib` 4.0.2, which now aligns the session collation with the `mysql` schema right after connect ([#1139](https://github.com/Linuxfabrik/monitoring-plugins/issues/1139))

 * mysql-innodb-buffer-pool-size: no longer aborts on MySQL 9.3 and newer. There `innodb_log_file_size` was removed, so the check now relies on `innodb_redo_log_capacity`
 * mysql-perf-metrics: no longer flags `innodb_log_file_size` and `innodb_log_files_in_group` as obsolete on MySQL 9.0 to 9.2, where they are still valid settings. They are reported only from MySQL 9.3 on, where they were actually removed
 * mysql-perf-metrics: the `innodb_io_capacity` check no longer raises false alarms on virtualised or network-backed storage (Ceph, cloud volumes), where the disk auto-detection misreads slow devices as fast local SSDs. It now runs only when `--storage-type=ssd` is set explicitly, and recommends sizing the value to the disk's measured IOPS instead of a fixed target

 * mysql-logfile: prefers `performance_schema.error_log` on MySQL 8.0.22+ (works remote). Bug fix: docker/podman/kubectl sources read container logs. Severity matched via `[ERROR]`/`[Warning]` tags
 * mysql-logfile: empty log file is now consistently STATE_OK regardless of whether `--server-log` was set (was STATE_UNKNOWN in auto-detect mode). Typical right after logrotate fires
 * mysql-memory: bug fix on `max_tmp_table_size`. Galera GCache counted on cluster nodes. New `--warning` (85%) / `--critical` (95%). `--lengthy` shows full breakdown. New perfdata

 * mysql-perf-metrics: warn when a deprecated config variable was explicitly set via `my.cnf` or `SET GLOBAL` (compile-time defaults stay silent). New perfdata `mysql_deprecated_config_variables`
 * mysql-perf-metrics: also check `innodb_snapshot_isolation` (MariaDB), and the two storage-type-aware InnoDB knobs `innodb_flush_neighbors` and `innodb_io_capacity`. New `--storage-type=auto|ssd|hdd|skip` parameter (auto reads `/sys/block` when the plugin runs on the database host)
