Fix constant names and typos in aioble examples and deepcopy function

[Josverl]

This PR combines a few rather minor fixes of typos in documentation and scripts.

• Update the aioble example to use the correct advertising interval constant name.
• Correct the README to reference the appropriate public address constant.
• Fix a typo in the deepcopy function to reference the correct dispatch table.

Fixes #1055, #699, #952

Thanks for this, there are some good fixes here.

I approve all commits except the RST formatting one.

I really don't think we should be using RST formatting here.

.Rst dropped

Why not 4 space indent like the other example code reformatted in this PR?

[Josverl]

thanks, missed that

The rst formatting was a side effect of the work I started with @jimmo to see if/how it would be possible to generate documentation pages from the source files.
Some of the existing docstrings were half-and-half RST and plaintext with a bit of .MD as well.

I have reverted the RST formatting to plaintext.

For a separate PR:
Using Sphinx-AutoAPI it should be rather simple to add documentation for the 3 categories of modules (micropython - stdlib - community) to the existing documentation. IMO That would close a discoverability and documentation gap.
Sphinx + Auto-API should be able to handle a mix of RST and MarkDown formats by enablingMyST as well.
