Update to golangci-lint version 1.43.0

The currently latest `golangci-lint` version 1.43.0 [1] introduced new
linters and updated supported ones:

1. tagliatelle [2] (v1.40.0 [3]) - Handles `struct` tags name casing.
   This linter is disabled by default, but will be enabled for this
   template to improve consistency across tag names.
2. errorlint [4] (v1.40.0 [3]) - This linter has been disabled in
   GH-39 [22] due to prevent false-positive errors, but will be enabled
   again with the newly introduced `errorf` option [5] being disabled to
   prevent this from happening again while still taking advantage of the
   `assert` and `comparison` checks.
3. wrapcheck [6] (v1.40.0 [3]) - This linter is known to cause
   false-positive errors for the main module (`go list -m`) of the
   repository where `golangic-lint` is being run, but in
   version `2.3.0` [7] the `ignorePackageGlobs` option was added that
   allows to ignore packages by pattern.
   Therefore in each project the main module should be added as
   wildcard. Also see tomarrell/wrapcheck#2 [8] for details and
   discussions about this known problem.
4. golint [9] (v1.40.1 [10]) - Remove deprecated linter.
   4.1 The recommended drop-in replacement is revive [21] which is
   disabled by default, but will be enabled for this template.
5. gofumpt [17] (v1.42.0 [16]) - Add the `lang-version` with value set
   to `1.17` to target the (currently) latest Go version.
6. bidichk [11] (v1.43.0 [12]) - Checks for dangerous unicode character
   sequences. This linter is disabled by default, but will be enabled
   for this template to prevent "trojan source" bugs.
7. nilnil [13] (v1.43.0 [12]) - Checks that there is no simultaneous
   return of `nil` error and an invalid value.
   This linter is disabled by default, but will be enabled for this
   template to prevent ambiguous returns.
8. tenv [14] (v1.43.0 [12]) - Detects using `os.Setenv` instead of
   `t.Setenv` since Go 1.17.
   This linter is disabled by default, but will be enabled for this
   template to prevent errors in tests.
9. contextcheck [15] (v1.43.0 [12]) - Checks if functions whether use a
   non-inherited context.
   This linter is disabled by default, but will be enabled for this
   template to broken call chains and loss of context information.
10. lll [18] - Add the `tab-width` option with value set to `2` to use
    two spaces for the width of one tab.
11. gci [19] - Add the comma-separated [list of prefixes for local
    package imports][20] to be put after 3rd-party packages.
