swift-argument-parser version issue.

[tarunon]

In the last two weeks, there has been a major update to swift-argument-parser, and several apple tools (e.g. swift-format) take the version.
Therefore, if we try to use the same Package.swift for license-plist and apple tools, an error will occur.

error: Dependencies could not be resolved because root depends on 'swift-format' 0.50500.0..<1.0.0 and root depends on 'LicensePlist' 3.14.2..<4.0.0.
'LicensePlist' is incompatible with 'swift-format' because no versions of 'swift-format' match the requirement 0.50500.1..<1.0.0.
'LicensePlist' is incompatible with 'swift-format' because 'LicensePlist' >= 3.12.0 depends on 'swift-argument-parser' 0.3.2..<1.0.0 and 'swift-format' 0.50500.0 depends on 'swift-argument-parser' 1.0.1..<1.1.0.
