[BUG] `--pretty=false` doesn't have any effect on TOML

[n-badtke-cg]

Describe the bug
I want to use the flag --pretty=false to get the same output from dasel as the input TOML is but the flag has no effect.

To Reproduce
Steps to reproduce the behavior:

0. (Example) Input file pyproject.toml:

   [build-system]
   requires = [
       "setuptools",
       "wheel"
   ]
   build-backend = "setuptools.build_meta"
   
   [project]
   name = "project_name"
   authors = [
       { name = "Dummy Dude", email = "dummy.dude@mail.world" }
   ]
   license = { text = "Apache License 2.0" }
   description = "A Python project"
   dynamic = [
       "version"
   ]
   requires-python = "~=3.13"
   
   # required by poetry but unused due to usage of setuptools
   [tool.poetry]
   version = "0"
   
   [project.readme]
   file = "README.md"
   content-type = "text/markdown"
   
   [project.entry-points.project_name]
   provider_info = "package_name.__init__:get_package_info"
   
   [tool.setuptools]
   include-package-data = false
   
   [tool.setuptools.dynamic]
   version = { attr = "package_name.__version__" }
   
   [tool.setuptools.packages.find]
   exclude = [
       "*tests.*",
       "*tests"
   ]

1. Commands:

   dasel -r toml --pretty=false -f pyproject.toml

   and also

   dasel put -r toml --pretty=false -f pyproject.toml -v '0.1.0' .tool.poetry.version

2. See different outputs than input contents:

   [build-system]
     build-backend = 'setuptools.build_meta'
     requires = ['setuptools', 'wheel']
   
   [project]
     description = 'A Python project'
     dynamic = ['version']
     name = 'project_name'
     requires-python = '~=3.13'
   
     [[project.authors]]
       email = 'dummy.dude@mail.world'
       name = 'Dummy Dude'
   
     [project.entry-points]
       [project.entry-points.project_name]
         provider_info = 'package_name.__init__:get_package_info'
   
     [project.license]
       text = 'Apache License 2.0'
   
     [project.readme]
       content-type = 'text/markdown'
       file = 'README.md'
   
   [tool]
     [tool.poetry]
       version = '0'
   
     [tool.setuptools]
       include-package-data = false
   
       [tool.setuptools.dynamic]
         [tool.setuptools.dynamic.version]
           attr = 'package_name.__version__'
   
       [tool.setuptools.packages]
         [tool.setuptools.packages.find]
           exclude = ['*tests.*', '*tests']

Expected behavior
The content of the output is matching the input content.

Desktop

• OS:

  > lsb_release -a
  No LSB modules are available.
  Distributor ID: Ubuntu
  Description:    Ubuntu 24.04.2 LTS
  Release:        24.04
  Codename:       noble
  

• Version: v2.8.1

Additional context
The pyproject.toml may get smaller and also more efficient but in automated CI/CD pipelines it is crucial to have the option to leave the contents as provided.

PS
Love the tool <3

Side note: the comment at .tool.poetry also gets omitted which is not desired but this is already mentioned in #178 : #178 (comment)
