Throw `GitHubProjectInvalidValueError` error when date field is set to invalid value

### Please avoid duplicates

- [X] I checked [all open bugs](https://github.com/gr2m/github-project/issues?q=is%3Aissue+is%3Aopen+label%3Abug) and none of them matched my problem.

### Reproducible test case

_No response_

### Please select the environment(s) that are relevant to your bug report

- [X] Browsers
- [X] Node
- [X] Deno

### Versions

v5.3.1

### What happened?

```
GraphqlResponseError: Request failed due to following response errors:
- Column value must be a valid value for date column
```

We should instead throw a `GitHubProjectInvalidValueError`

### Would you be interested in contributing a fix?

- [ ] yes

Start by locating the date-field handling and the code that currently surfaces GraphqlResponseError for invalid column values. Reproduce the reported invalid-date case in the browser, Node, or Deno environment, then verify that it raises GitHubProjectInvalidValueError instead.
