[BUG] Does not support Oracle placeholders like :1, :2, :name.

[ledel037]

Bug Description

Does not support Oracle placeholders like :1, :2, :name.

1. unexpected token: COLON (':')

Code Example

	astNode, err := gosqlx.ParseWithDialect(sql, keywords.DialectOracle)
	if err != nil {
		return nil, fmt.Errorf("failed to parse SQL: %w", err)
	}

SQL Query

       sql := fmt.Sprintf(`SELECT %s FROM %s WHERE virtual_fund_id = :1`, virtualFundSelectColumns, virtualFundTable)
        rows, err := r.client.ExecuteQuery(ctx, sql, []interface{}{fundID})

Environment

• OS: centos 7.9
• Go Version: 1.24.13
• GoSQLX Version: 1.12.1

Additional Context

I can only use Go version 1.24.13 for now, so I have to stick with GoSQLX 1.12.1. I haven't verified whether later versions are supported.
