lint fixes

[mts1715]

Note: should be merged before fix wrong authorization PR #143

• fixed problems that was found by flow cadence lint.
• added lint stage before test stage in the CI workflow

---

Update: problem bellow was solved in onflow/cadence-tools#586 .

But some problems were left unresolved due to a bug with the linter:

var out: [UInt8] = []    // type annotation is redundant, type can be inferred
var out = []             // cannot infer type: requires an explicit type annotation. add an explicit type annotation to resolve the ambiguity
var out = [] as [UInt8]  // static cast is redundant

Also, it's impossible to use a long string template across multiple lines, so in order to prevent long lines, it should be written like this:

panic("Deposit token type \(self.depositVaultType.identifier) has not been onboarded to the VM bridge - "
                .concat("Ensure the Cadence token type is associated with an EVM contract via the VM bridge"))

But the linter suggests: string concatenation can be replaced with string template

Looks good overall!
Left a few suggestions for using the type-annotation over casting/conversion.

Nice! Thanks for cleaning this up

LGTM! Seems there's still an open question from Bastian ragarding the authorization/entitlements change. Apart from that, everything else looks good!
