wslc: alias -f to --format on inspect commands for docker parity - #41463

Summary of the Pull Request

Adds docker's -f short alias for --format on the inspect command family, so wslc inspect -f json <id> works the same way docker inspect -f does.

Docker defines this in cli/command/system/inspect.go:

flags.StringVarP(&opts.format, "format", "f", "", flagsHelper.InspectFormatHelp)

wslc already accepted --format on all five inspect commands but registered it with NO_ALIAS, so the short form was rejected.

Detailed Description of the Pull Request / Additional comments

Single-line change in ArgumentDefinitions.h: ArgType::InspectFormat gains the f alias.

-_(InspectFormat,    "format",               NO_ALIAS,         Kind::Value,      JsonIndent,   ...)
+_(InspectFormat,    "format",               L"f",             Kind::Value,      JsonIndent,   ...)

Because InspectFormat is a distinct ArgType from the general-purpose Format (used by the list
commands, where docker reserves -f for --filter), this picks up the alias only on the five
commands that register it:

• wslc inspect
• wslc container inspect
• wslc image inspect
• wslc network inspect
• wslc volume inspect

None of those commands register --filter, --follow, --file or --force, so there is no
alias collision. The existing AllCommands_NoAmbiguousArgumentNamesOrAliases unit test walks the
whole command tree and enforces this, and it still passes.

No behavior changes beyond accepting the short spelling — the alias flows through the same
validation and conversion path as the long name, so -f json is accepted and -f table /
-f badformat are rejected with the existing error message.

Localization

No new user-facing strings. The alias reuses the existing
WSLCCLI_InspectFormatArgDescription description, which already renders in help output.

Validation Steps Performed

Added tests only; no existing tests needed changing.

Parser cases (CommandLineTestCases.h) — 16 new table-driven cases covering the alias on every
inspect command, including the adjoined form (-f=json), the rejected values (-f table,
-f badformat) and the missing-value case (inspect -f).

Unit tests

• InspectCommands_FormatArgumentHasDockerAlias — asserts all five inspect commands register
  --format with alias f.
• Value_AliasCarriesValue — drives the parser state machine to confirm the alias binds its value
  to ArgType::InspectFormat and does not swallow the following positional.

E2E tests

• WSLCE2E_Inspect_FormatAlias_MatchesLongName — asserts -f json and --format json produce
  byte-identical compact JSON.
• WSLCE2E_Inspect_FormatAlias_InvalidValue — asserts the alias runs the same validation.
• WSLCE2E_Image_Inspect_FormatAlias_MatchesLongName — same equivalence check on a subcommand.

Build is clean.
