fix a bug in the .readthedocs.yml file

[h-chmeruk]

The test for Read the Docs failed in the PR#927 of the pyfar package because the python version in the tools in the .readthedocs.yml file was not enclosed in quotation marks.

Changes proposed in this pull request:

• Enclose {{ latest_python_version }} in the quotation marks
• Adjust the test function in the test_copier.py file

thanks for catching, not sure of the quotes are the issue. see below:

Suggested change

	{% if 'libsndfile1' in apt_packages -%}
	apt_packages:
	- libsndfile1
	{% if 'libsndfile1' in apt_packages -%}
	apt_packages:
	- libsndfile1

I think the bug is the intent of apt_packages: it does not have any spaces in front, but two are requried.

Oh, indeed, thank you for pointing that out!
I think the absence of quotation marks was also a major issue, at least that’s what the error message on ReadTheDocs said...

[ahms5]

Thank you, I just noticed an other point, sorry for not mentioning it earlier,

[ahms5]

maybe also add this in order to prevent that error in future.

Suggested change

	'python: "3.14"',
	'python: "3.14"',
	' apt_packages:',

[ahms5]

Sorry, I did not see it earlier, I think we can loop through all apt_packages here in the list below. In this way every package in apt_packages will be installed, which is also the intended use.

[ahms5]

almost there, thank you, I think we should add a test for empty apt_packages. what do you think?

[h-chmeruk]

@ahms5, yeah, sounds good, I'll add it
