## 🐛 Bug Report

Running i18next-parser on a JSX tag that spreads attributes results in the following error.

```
TypeError: Cannot read properties of undefined (reading 'escapedText')

## To Reproduce

```js
<Trans>Please <a {...hrefProps}>click here.</a></Trans>
```

## Expected behavior

i18next-parser cleanly extracts the translation string.

## Your Environment

- *runtime version*: Node 18.16.1
- *i18next version*: i18next-parser 8.7.0
- *os*: Mac
- *any other relevant information*: This may have been introduced in #862.
