hatchling version requirements is incorrect

### Subject

The `hatchling>=1.6.0,<2` version requirement is incorrect and results in build failures with any hatchling version between 1.6.0 and 1.27.0 excluded.

The error is as follow:

```
TypeError: Field `project.license-files` must be a table
```

This is due to [this change](https://github.com/pypa/hatch/pull/1790) being required to address an [issue in the project's license declaration](https://github.com/pypa/hatch/issues/1715).

### Environment

I'm running NixOS on the latest `unstable`.

```text
OS Linux-6.15.4-x86_64-with-glibc2.40
Python 3.13.4
OpenSSL 3.4.1 11 Feb 2025
urllib3 2.5.1.dev4
```

### Steps to Reproduce

1. Download the project source code (commit `98a60f9c26a4d64cf18c7e004b9adda4303bc28c` at this time of writing)
2. Run `hatchling build`

### Expected Behavior

Successful build, with an output like the following:

```text
[sdist]
dist/urllib3-2.5.1.dev5.tar.gz

[wheel]
dist/urllib3-2.5.1.dev5-py3-none-any.whl
```

### Actual Behavior

With any hatchling version between 1.6.0 and 1.27.0 excluded (for this trial, I used 1.25.0):

```text
TypeError: Field `project.license-files` must be a table
```
