Fix version parsing

[kmikov]

Fix version parsing when the version number is not on the first line due to plugins.

Additional info:

Tshark supports lua plugins in ~/.local/lib/wireshark/plugins/
If you have a lua plugin that prints some info it will be displayed everytime tshark starts. For example like this:

$ tshark -v
Loading test.lua
TShark (Wireshark) 4.2.2 (Git v4.2.2 packaged as 4.2.2-1.1build3).

Copyright 1998-2024 Gerald Combs <[email protected]> and contributors.

This gives the following exception:

Traceback (most recent call last):
  File "/home/kmikov/GIT/python_test/test.py", line 3, in <module>
    print(get_tshark_version())
          ^^^^^^^^^^^^^^^^^^^^
  File "/home/kmikov/GIT/python_test/.venv/lib/python3.12/site-packages/pyshark/tshark/tshark.py", line 85, in get_tshark_version
    raise TSharkVersionException("Unable to parse TShark version from: {}".format(version_line))
pyshark.tshark.tshark.TSharkVersionException: Unable to parse TShark version from: Loading test.lua

The fix checks every line and searches for the first hit with the regex. Of course someone can print another version numbers from the lua script, but at least pyshark won't throw an exception.

Optional regex to further narrow the version

Suggested change

	pattern = r'.*\s(\d+\.\d+\.\d+).*' # match " #.#.#" version pattern
	pattern = r'^TShark.*?\s(\d+\.\d+\.\d+).*' # match " #.#.#" version pattern
