Some identifiers get converted to uppercase with keywordCase:upper

Input data

Which SQL and options did you provide as input?

create table player_match_details(
  name varchar(150),
  match varchar(150),
  score int
);

Expected Output

CREATE TABLE player_match_details(
  name varchar(150),
  match varchar(150),
  score int
);

Actual Output

CREATE TABLE player_match_details(
  name varchar(150),
  MATCH varchar(150),
  score int
);

Usage

• How are you calling / using the library?

import { format } from 'sql-formatter';

• What SQL language(s) does this apply to?

  {
      language: 'sql',
      indent: '',
      uppercase: true,
      linesBetweenQueries: 2
   }

• Which SQL Formatter version are you using?
  15.3.1

No files or tests are identified in the issue. Start by reproducing the supplied CREATE TABLE example with the SQL formatter and its uppercase/keywordCase options, then trace the formatting path that changes MATCH while preserving the other identifiers. Done means the expected output is produced without uppercasing the column name.
