dev: format linter descriptions inside help command

[alexandear]

This is for consistency with the documentation.

Before:

$ go run ./cmd/golangci-lint/ help linters
Enabled by default linters:
errcheck: errcheck is a program for checking for unchecked errors in Go code. These unchecked errors can be critical bugs in some cases [fast: false, auto-fix: false]
gosimple: Linter for Go source code that specializes in simplifying code [fast: false, auto-fix: false]
govet: Vet examines Go source code and reports suspicious constructs. It is roughly the same as 'go vet' and uses its passes. [fast: false, auto-fix: false]
ineffassign: Detects when assignments to existing variables are not used [fast: true, auto-fix: false]
staticcheck: It's a set of rules from staticcheck. It's not the same thing as the staticcheck binary. The author of staticcheck doesn't support or approve the use of staticcheck as a library inside golangci-lint. [fast: false, auto-fix: false]
unused: Checks Go code for unused constants, variables, functions and types [fast: false, auto-fix: false]

Disabled by default linters:
asasalint: check for pass []any as any in variadic func(...any) [fast: false, auto-fix: false]
asciicheck: checks that all code identifiers does not have non-ASCII symbols in the name [fast: true, auto-fix: false]
bidichk: Checks for dangerous unicode character sequences [fast: true, auto-fix: false]
...

$ go run ./cmd/golangci-lint/ help linters
