CI fails on a new go version profile: regex-based tokenizer broke down on 1.13 but works on 1.12 🤦‍♂

$ go test -run TestTokenize ./internal/tokenizer
--- FAIL: TestTokenize (0.00s)
    --- FAIL: TestTokenize/content (0.00s)
        require.go:157:
            	Error Trace:	tokenize_test.go:110
            	Error:      	Not equal:
            	            	expected: 190
            	            	actual  : 166
            	Test:       	TestTokenize/content
            	Messages:   	token' slice length = 190, want 166

$ gvm use go1.12.1
$ go test -run TestTokenize ./internal/tokenizer
ok  	github.com/bzz/enry/v2/internal/tokenizer	0.024s

will move new CI profile 007be3c to a separate PR.

Merging as CI is green.
