docs: add a more precise example in enum doc (GH-121015)
* docs: add a more precise example
Previous example used manual integer value assignment in class based declaration but in functional syntax has been used auto value assignment what could be confusing for the new users. Additionally documentation doesn't show how to declare new enum via functional syntax with usage of the manual value assignment.

[3.12] Prefer "similar" over "equivalent" in tutorial (GH-125343) (GH-125373)
Prefer "similar" over "equivalent" in tutorial (GH-125343)
In the datastructures tutorial doc, some operations are described as
"equivalent to" others. This has led to some user-confusion -- at
least in the Discourse forums -- about cases in which the operations
differ.
This change doesn't systematically eliminate the word "equivalent"
from the tutorial. It just substitutes "similar to" in several cases
in which "equivalent to" could mislead users into expecting exact
equivalence.

[3.12] gh-126105: Fix crash in `ast` module, when `._fields` is deleted (GH-126115)
Previously, if the `ast.AST._fields` attribute was deleted, attempts to create a new `as`t node would crash due to the assumption that `_fields` always had a non-NULL value. Now it has been fixed by adding an extra check to ensure that `_fields` does not have a NULL value (this can happen when you manually remove `_fields` attribute).

There was a deadlock when `ProcessPoolExecutor` shuts down at the same
time that a queueing thread handles an error processing a task.
Don't use `_shutdown_lock` to protect the `_ThreadWakeup` pipes -- use
an internal lock instead. This fixes the ordering deadlock where the
`ExecutorManagerThread` holds the `_shutdown_lock` and joins the
queueing thread, while the queueing thread is attempting to acquire the
`_shutdown_lock` while closing the `_ThreadWakeup`.
