Merge split code blocks in README to remove blank line between code and output

[Copilot]

Two README examples had their code and printed output split across separate fenced code blocks, causing an unwanted blank line between them in the rendered output.

Removed the redundant closing ``` and opening ```python delimiters at both locations, merging each pair into a single continuous block:

config = FortranNMLParser().parse(text)
print(config)
&data_nml
 parameterA = 1
 parameterB = 'abc'
/

<issue_title>Remove blank line separating printed output from the code in README.md</issue_title>
<issue_description>These two python code segments could be merged into one, and that would remove the blank line between the code example and the printed output.

Similar issue with the next code example and printed output - here

Solution is to remove both sets of closing and opening code backticks. </issue_description>
