dev: adjust replacement msg for nosnakecase

[alexandear]

The PR changed replacement string for the deprecated nosnakecase linter from revive(var-naming) to revive 'var-naming' to be consistent with the replacement string govet 'fieldalignment' for maligned.

Before:

❯ golangci-lint run -E nosnakecase -E maligned -v --disable-all --no-config

WARN [runner] The linter 'nosnakecase' is deprecated (since v1.48.1) due to: The repository of the linter has been deprecated by the owner. Replaced by revive(var-naming). 
WARN [runner] The linter 'maligned' is deprecated (since v1.38.0) due to: The repository of the linter has been archived by the owner. Replaced by govet 'fieldalignment'. 

After:

❯ ./golangci-lint run -E nosnakecase -E maligned -v --disable-all --no-config

WARN [runner] The linter 'nosnakecase' is deprecated (since v1.48.1) due to: The repository of the linter has been deprecated by the owner. Replaced by revive 'var-naming'. 
WARN [runner] The linter 'maligned' is deprecated (since v1.38.0) due to: The repository of the linter has been archived by the owner. Replaced by govet 'fieldalignment'.
