[BUG] Error parsing dynamicFilter in Excel table: "Unexpected xml node in parseOpen"

## 🐛 Bug Report

Full repo to easily reproduce this bug is available here: https://github.com/examind-ai/exceljs-dynamicfilter-bug

Lib version: 4.4.0

ExcelJS fails to parse Excel files containing dynamicFilter elements in table XML with the error: Unexpected xml node in parseOpen. This occurs when Excel tables use dynamic filters (like "Above Average"), but only affects table-level filters - worksheet-level dynamic filters parse successfully.

## Steps To Reproduce

1. Open Excel
2. Create a new workbook
3. Add sample data

ID | Age
-- | --
1 | 10
2 | 11
3 | 12
4 | 13
5 | 14
6 | 15
7 | 16
8 | 17
9 | 18
10 | 19

4. Convert to a table: `Insert` -> `Table`
5. Select the `Age` filter and choose: `Number filters` -> `Above Average`

Then try to load that file into exceljs with:

```javascript
const workbook = new ExcelJS.Workbook();
await workbook.xlsx.readFile('excel-file.xlsx');
```

## The expected behaviour:

Expect ExcelJS to not throw an exception. Instead, it results in this exception:

```
exceljs-dynamicfilter-bug\node_modules\exceljs\lib\xlsx\xform\table\filter-column-xform.js:72
throw new Error(`Unexpected xml node in parseOpen: ${JSON.stringify(node)}`);
