We can use `(*regexp.Regexp).MatchString` instead of
`(*regexp.Regexp).Match([]byte(...))` to avoid unnecessary `[]byte`
conversions and reduce allocations. A one-line change for free
performance gain.
Benchmark:
```go
func BenchmarkMatch(b *testing.B) {
for i := 0; i < b.N; i++ {
if match := envOnlyRe.Match([]byte("{{ .Env.FOO }}")); !match {
b.Fail()
}
}
}
func BenchmarkMatchString(b *testing.B) {
for i := 0; i < b.N; i++ {
if match := envOnlyRe.MatchString("{{ .Env.FOO }}"); !match {
b.Fail()
}
}
}
```
Result:
