Update repo about text

Maybe change the repo About text from:

```text
A fork of sqlite-minutils for apsw
```

to:

```text
A fork of sqlite-utils, using apsw as the sqlite interface.
```

This would be more inline with the [docs](https://answerdotai.github.io/apswutils/):

```text
A fork of the sqlite-utils package with the CLI removed and using apsw as the sqlite interface.
```
