Add pronunciation of Mac Option key symbol "⌥"

[dbjorge]

Link to issue number:

n/a (minor/trivial change)

Summary of the issue:

NVDA doesn't announce the symbol that macs use to represent the mac "Option" key ("⌥") (see Mac keyboard shortcuts documentation).

Description of user facing changes

Adds a symbol description for this symbol ("mac Option key" announced at "none" level and up, similar to the existing entry for "mac Command key" at the "none" level for symbol "⌘").

Description of development approach

Followed the "Defining Symbol Information" developer documentation, using the existing "mac Command key" entry and similar recent PR #14548 as examples

Testing strategy:

Didn't attempt to adjust any automated tests (assumed they were already present generally for symbol pronunciation). Manually verified reading by:

1. runnvda.bat from this branch
2. Browse to Mac keyboard shortcuts docs
3. Read through the content under the "Mac keyboard shortcuts" H1, particularly the list item with content "Option (or Alt) ⌥"
4. Verify that the symbol is read out as "mac Option key" as expected
5. Change NVDA's "Settings > Speech > Punctuation/symbol level" to "none" and repeat above steps

Known issues with pull request:

Mac commonly uses a few other symbols to represent keyboard modifiers (eg, when displaying keyboard shortcut hints), per the Mac keyboard shortcuts documentation. I've left the other cases alone because they either:

• Already have a comparable entry ("Command ⌘")
• Are usually represented as an image, not a character symbol ("Fn ")
• Already have more general symbol names that would be applicable in more contexts ("Shift ⇧", "Caps Lock ⇪", "Control ^")

Hi @seanbudd ,

Just wanted to give a friendly ping on this and to clarify that this PR is marked as a "Draft" only because that's what the PR template suggests to do - I think it's ready for review. Is there anything further action you'd like me to take to help move this forward?
