This reverts commit aeb98303293570ba682ea933a4e9501a11a3aa99.
There are some cases that nolinter fixer wasn't handling properly or expectedly (#1579, #1580, #1581) so we'll fix those in a new attempt.
Treat Go source files as plain text files by misspell: it allows detecting
issues in strings, variable names, etc. Also, it's the default mode of
a standalone misspell tool.
Also, implement richer and more stable auto-fix of misspell issues:
now it can fix multiple issues in one line.
