Removes support for adding aliases to analyzers. Indices created pre 5.x
that have analyzer aliases in their analysis settings will still work, but
any attempts to create an alias for analyzers in newly created indices
will result in an
IllegalArgumentException
.As a result, the setting
index.analysis.analyzer.{analyzerName}.alias
isno longer supported.
Note that the documentation for this setting was already removed in #18269.
Closes #18244
