fix: Bad log spacing depending on the FORMAT and COLORS options used

[somethingSTRANGE]

fixes: #4630

Previously, when colors were enabled, the log message always had a single space padded to the left, otherwise a single space was always padded to the right. This padding of the full log message seemed to be entirely unnecessary. Also, there was no explicit space set to appear between the timestamp and the log message, although when colors were enabled, the padding mentioned above would include a space, but only in that case.

Now, there's always a space between the timestamp and the log message, and there are no unnecessary spaces inserted at the beginning or end of the log message. I tested locally with all four combinations of format: pretty, format: pretty-timestamped, colors: false, and colors: true, and I believe the spacing now appears correct.

format: pretty with colors: false or colors: true:

Lint Error:
Error: 6:39 error 'padLeft' is defined but never used @typescript-eslint/no-unused-vars
/home/runner/work/verdaccio/verdaccio/packages/logger/logger-prettify/src/formatter.ts

'padLeft' is still defined but never used elsewhere in code. It was only used once in formatter.ts, but that use was removed with commit 6f81014.

Should the entire 'padLeft' function and all references to it (test, exports, etc.) be removed?

[mbtools]

Remove padLeft completely. We can always add it back later if necessary.

Also include a changeset, please
