doc: Corrected Typos in Documentation

[ppyordanov]

Scanned the whole source code for typing errors and corrected. Added a translation correction.

If you're going to fix typos, can you please fix all of them as seen in the spelling linter script test/lint/lint-spelling.sh, e.g. I believe:

src/core_read.cpp:131: presense ==> presence
src/net_processing.h:68: anounce ==> announce
src/netaddress.h:486: compatiblity ==> compatibility
src/wallet/walletdb.cpp:429: Crypted ==> Encrypted
src/test/validation_tests.cpp:78: excercise ==> exercise
test/functional/feature_nulldummy.py:63: unnecssary ==> unnecessary

and update test/lint/lint-spelling.ignore-words.txt to ignore all of the current false positives.

Don't modify upstream files, generated files, historical release notes, subtrees or any translations. Remove any @ mentions from the PR body.

Note also there is already this PR in progress of review. #20762

There may well be some to-dos for a follow up PR though.

[jonatack]

Concept ACK for any remaining ones after doing #20836 (comment) and #20762 -- looks like you found some.

Noisy labels too. A maintainer needs to reduce the Labels to just Docs

Thanks for your contribution. However to move things along I'm going to fix this up and consolidate it with some other changes. Your changes will still be attributed to you.
