Please see <https://bugs.r-project.org/show_bug.cgi?id=18548> for the
background. The documentation has always said that the input needs to be
a character vector. Implicit conversion of numeric input to character is
affected by R options (OutDec and scipen), but it is also error-prone in
this context:
R> package_version("1.3") > 1.20
[1] TRUE
This now warns for a good reason in my opinion.

Dear R devs,
I installed the recent devel R to test a package error when I intercept this
warning when loading packages:
```
Warning in .make_numeric_version(x, strict,
.standard_regexps()$valid_numeric_version) :
invalid non-character version specification 'x' (type: double)
```
After a long debugging, I realize that `numeric_version` in base does not
support numerical input x by default now.
A reproducible example:
R 4.4
```
numeric_version(1.5)
Warning in .make_numeric_version(x, strict,
.standard_regexps()$valid_numeric_version) :
invalid non-character version specification 'x' (type: double)
[1] ‘1.5’
```
R 4.3.1
```
numeric_version(1.5)
[1] ‘1.5’
```
According to help document, `strict=TRUE` should result in errors, then the 4.3
behavior was actually incorrect. According to pkgload maintainer, Kurt has sent
him an email to fix this, suggesting this on-going change is intentional.
May I ask is there any benefit of changing the behavior?
Thanks,
- D
