Use Poetry in RTD

[Alessandro Candido]

These deps were specified in the following way:

qibocal/pyproject.toml

Lines 36 to 42 in 8decaec

 # docs dependencies (for readthedocs, https://github.com/readthedocs/readthedocs.org/issues/4912#issuecomment-664002569) 
 Sphinx = { version = "^5.0.0", optional = true } 
 furo = { version = "^2023.3.27", optional = true } 
 sphinxcontrib-bibtex = { version = "^2.4.1", optional = true } 
 recommonmark = { version = "^0.7.1", optional = true } 
 sphinx_markdown_tables = { version = "^0.0.17", optional = true } 
 sphinx-copybutton = { version = "^0.5.1", optional = true } 

just because of the cited limitation of RTD.

This limitation is not present any longer since a while.
https://docs.readthedocs.io/en/stable/build-customization.html#install-dependencies-with-poetry
So, we should just rely on the Poetry group,

qibocal/pyproject.toml

Lines 66 to 75 in 8decaec

 [tool.poetry.group.docs] 
 optional = true 
  
 [tool.poetry.group.docs.dependencies] 
 Sphinx = "^5.0.0" 
 furo = "^2023.3.27" 
 sphinxcontrib-bibtex = "^2.4.1" 
 recommonmark = "^0.7.1" 
 sphinx_markdown_tables = "^0.0.17" 
 sphinx-copybutton = "^0.5.2" 

and drop the related extra.

qibocal/pyproject.toml

Lines 96 to 103 in 8decaec

 docs = [ 
   "sphinx", 
   "furo", 
   "sphinxcontrib-bibtex", 
   "recommonmark", 
   "sphinx_markdown_tables", 
   "sphinx-copybutton", 
 ]

(btw, RTD is not even our main platform any longer)
