The time zone "Europe/Amsterdam" is of class `TimeZones.Class(:LEGACY)`

[rikhuijzer]

I'm unable to run code which refers to tz"Europe/Amsterdam" with TimeZones.jl v1.9.1:

julia> using TimeZones

julia> tz"Europe/Amsterdam"
ERROR: LoadError: ArgumentError: The time zone "Europe/Amsterdam" is of class `TimeZones.Class(:LEGACY)` which is currently not allowed by the mask: `TimeZones.Class(:FIXED) | TimeZones.Class(:STANDARD)`

This is unexpected since Europe/Amsterdam is a commonly used timezone. The release notes of tz show no mention of the deprecation of the timezone, apart from the following note:

Finish moving to 'backzone' the location-based zones whose timestamps since 1970 are duplicates; adjust links accordingly. This change ordinarily affects only pre-1970 timestamps, and with the new PACKRATLIST option it does not affect any timestamps. In this round the affected zones are Antarctica/Vostok, Asia/Brunei, Asia/Kuala_Lumpur, Atlantic/Reykjavik, Europe/Amsterdam, Europe/Copenhagen, Europe/Luxembourg, Europe/Monaco, Europe/Oslo, Europe/Stockholm, Indian/Christmas, Indian/Cocos, Indian/Kerguelen, Indian/Mahe, Indian/Reunion, Pacific/Chuuk, Pacific/Funafuti, Pacific/Majuro, Pacific/Pohnpei, Pacific/Wake and Pacific/Wallis, and the affected links are Arctic/Longyearbyen, Atlantic/Jan_Mayen, Iceland, Pacific/Ponape, Pacific/Truk, and Pacific/Yap.

And indeed the same error shows up for the zones listed in the note. For example:

julia> tz"Pacific/Ponape"
ERROR: LoadError: ArgumentError: The time zone "Pacific/Ponape" is of class `TimeZones.Class(:LEGACY)` which is currently not allowed by the mask: `TimeZones.Class(:FIXED) | TimeZones.Class(:STANDARD)`

Is this behavior expected?
