Enums test fails on 32bit

[leso-kn]

Describe the bug
The enums_test.go test fails when run under 32-bit architectures (e.g. x86, armv7, armhf).

To Reproduce
Steps to reproduce the behavior (docker):

1. docker run --rm -ti -v $PWD:/repo --workdir /repo alpine
2. apk add go
3. make test
4. Tests fail with message:

   enums_test.go:24: 
        	Error Trace:	github.com/swaggo/swag/enums_test.go:24
        	Error:      	Not equal: 
        	            	expected: 64
        	            	actual  : 32
   

Expected behavior
The enums test should pass on 32-bit systems.

Screenshots

Your swag version
e.g. 1.8.12

Your go version
e.g. 1.20.6

Desktop (please complete the following information):

• OS: Alpine Linux
• Version: edge
• Tested Architectures: x86_64 (ok), riscv64 (ok), x86 (not ok), armv7 (not ok), armhf (not ok)

Additional context
Explanation: The test fails because it asserts the size of uint against 64, which is only true on 64-bit systems.
