Fix build warnings for Erlang/OTP 27

[bjosv]

Client: Erlang
Since erlfmt is a build dependency, and the currently used version generates build warnings with latest OTP 27, we lift its version.

Example of warnings that are fixed:

===> Compiling erlfmt
    ┌─ _build/default/plugins/erlfmt/src/erlfmt_parse.yrl:
    │
 96 │  node -> standalone_exprs exprs dot : {exprs, (?range_anno('$1', '$3'))#{dot => true}, '$2'}.
    │                                                                        ╰── Warning: expression updates a literal

     ┌─ _build/default/plugins/erlfmt/src/erlfmt_parse.yrl:
     │
 149 │      {record, (?range_anno('$1', '$3'))#{macro_record => true}, '$1', []}.
     │                                        ╰── Warning: expression updates a literal
...

Includes a formatting correction (legacy) that is verified to work with the script build/veralign.sh.

This change is additionally tested to work with older OTP 23 and 24.
