Several minor documentation issues

[andreas-hilti]

Description of the modifications

• Typo: https://composites.dpf.docs.pyansys.com/dev/index.html ("." too much):
  Refer to the Section Import Legacy Models on the official Ansys help. to learn how to convert legacy models.
• Typo: second example (Sampling Point): should be "built" instead of "build"
  Plots can be easily customized or build from scratch
• Typo: https://composites.dpf.docs.pyansys.com/dev/examples/gallery_examples/8_assembly_example.html
  should be "operate" instead of "operator"
  "The Composite Model helps to operator on the individual parts and to access all the data."
• Typo: https://composites.dpf.docs.pyansys.com/dev/api/_autosummary/ansys.dpf.composites.connect_to_or_start_server.html
  "I" instead of "If":
  I no arguments are passed a local server from the latest available installer is started.
• The ipynb contains strange text, for instance the second example: "The Sampling Point <ansys.dpf.composites.SamplingPoint>{.interpreted-text role="class"}" #108
• document return value: SamplingPoint.get_result_plots
• document return value. SamplingPoint.get_polar_plot
• the example is shown on a single line (hard to read) #109
  https://composites.dpf.docs.pyansys.com/dev/api/_autosummary/ansys.dpf.composites.SamplingPoint.add_results_to_plot.html
• here as well:
  https://composites.dpf.docs.pyansys.com/dev/api/_autosummary/ansys.dpf.composites.failure_criteria.CombinedFailureCriterion.html
• https://composites.dpf.docs.pyansys.com/dev/api/_autosummary/ansys.dpf.composites.connect_to_or_start_server.html
  "\" are missing:
  Ansys root path, for example C:Program FilesANSYS Incv231. Ignored if either port or ip are set.
• https://composites.dpf.docs.pyansys.com/dev/api/_autosummary/ansys.dpf.composites.failure_criteria.PuckCriterion.cfps.html
  Remove "Whether to consider" (sounds like it was a bool)?
  PuckCriterion.cfps: float
  Whether to consider inter-fiber strength reduction due to fiber parallel stresses.
• You should use the official version number:
  ansys-dpf-composites supports Ansys version 23.1 and later.
