Describe the bug

The argon2 password SPI has a configuration for the hash-length. This configuration's documentation is wrong.
The hash-length is documented to be set via the spi-password-hashing-argon2-type property, but it should be spi-password-hashing-argon2-hash-length.

The documentation comes from the getConfigMetaData() method, from the Argon2PasswordHashProviderFactory class.

What needs to change is:

builder.property()
.name(TYPE_KEY)
.type("int")
.helpText("Hash length")
.defaultValue(Argon2Parameters.DEFAULT_HASH_LENGTH)
.add();

into

builder.property()
.name(HASH_LENGTH_KEY)
.type("int")
.helpText("Hash length")
.defaultValue(Argon2Parameters.DEFAULT_HASH_LENGTH)
.add();

I can create a PR for this.

Version
