Doesn't work with Poetry 2.0 if pyproject doesn't have [tool.poetry]

[taconi]

In the latest version of poetry, the [tool.poetry] table is no longer mandatory.

Now it also reads the [proejct] table.

So, these two configurations are valid:

[project]
name = "test"
version = "0.1.0"

requires-python = ">=3.13,<4.0"
dependencies = [
    "numpy (>=2.2.1,<3.0.0)"
]

[tool.poetry]
package-mode = false

[tool.poetry.dependencies]
python = "^3.13"
numpy = "^2.2.1"

poetry.el/poetry.el

Lines 893 to 901 in 1dff0d4

	(defun poetry-find-project-root ()
	"Return the poetry project root if any."
	(or poetry-project-root
	(when-let* ((root (locate-dominating-file default-directory "pyproject.toml"))
	(pyproject-contents
	(with-temp-buffer
	(insert-file-contents-literally (concat (file-name-as-directory root) "pyproject.toml"))
	(buffer-string)))
	(_ (string-match "^\\[tool\\.poetry\\]" pyproject-contents)))

The poetry-find-project-root function only searches for [tool.poetry], I believe the adjustment should be in this function, but I don't have enough context of the project to know what it would be.

Maybe turn the poetry check command?

I encountered the same problem. I am currently adding an empty [tool.poetry] node to pyproject.toml to temporarily solve the problem. Waiting for maintainers to adjust the regular expression
