Subject: [PATCH] build: support flit-core 4 by migrating metadata to PEP 621

flit-core 4 removed the legacy `[tool.flit.metadata]` table:

    flit_core.config.ConfigError: The [tool.flit.metadata] table is no
    longer supported. Switch to the standard [project] table or require
    flit_core<4 to build this package.

Move the metadata to the standard `[project]` table:

- `dist-name` -> `name`, `author` -> `authors`, `description-file` ->
  `readme`, `requires` -> `dependencies`
- `module = "delinea"` -> `[tool.flit.module]`, since the module name
  differs from the distribution name
- version and summary keep coming from the module's `__version__` and
  docstring, now declared via `dynamic`
- the license classifier becomes the SPDX expression `Apache-2.0`
  (PEP 639), which needs flit_core >= 3.12
- the project URL moves to `[project.urls]`

Require `flit_core >=3.12,<5` instead of pinning an exact version, so a
future flit-core major does not break the build again.

The built metadata is unchanged apart from `License-Expression:
Apache-2.0` replacing the license classifier.
