DFParser cannot parse CopyIntoSnowflake

[osipovartem]

Describe the bug

DFParser::parse_sql_with_dialect(sql, dialect.as_ref())?

trying to parse COPY INTO .. as Statement::CopyTo even if we set "snowflake" dialect where Statement::CopyIntoSnowflake already supported.

The possible reason of the issue related to Keyword::COPY logic. We need to check if the next token != Keyword::INTO to pass such sql to sqlparser-rs

/// Parse a new expression
  pub fn parse_statement(&mut self) -> Result<Statement, ParserError> {
      match self.parser.peek_token().token {
          Token::Word(w) => {
              match w.keyword {
                  Keyword::COPY => {
                      self.parser.next_token();
                      self.parse_copy()
                  }
              }
          }
...

To Reproduce

No response

Expected behavior

With "snowflake" dialect COPY INTO statement should be parsed correctly as Statement::CopyIntoSnowflake
